We are coming to the end of another fall hunting season. If you are pursuing big game, such as Elk in the Rockies, you want a powerful cartridge that is also highly accurate. We like the 7mm for big game hunting as there are a wide variety of options — from the 7mm-08 up to the very large 7mm magnums. And Hornady’s new 7 PRC has quickly earned a following among hunters. In today’s Saturday Movie Showcase, we feature seven videos covering a wide selection of 7mm cartridge types including: 7mm-08 Rem, 7×57 Mauser, 7mm PRC, 7mm WSM, 7mm SAUM (aka RSAUM), 7mm Rem Mag, and 28 Nosler.
7mm PRC in Custom Rifle
The 7mm PRC was created by Hornady as part of the PRC series which includes the 6.5 PRC and 300 PRC. With a modern, non-belted magnum case design the 7mm PRC offers excellent power with good ballistics. The 7mm PRC can drive high-BC 175 grain bullets at 3000 FPS, making it very effective at putting down large game. This Precision Rifle Network video features a high-end custom 7mm PRC rifle built with a Terminus Zeus action, 29″ barrel, Grayboe stock, Triggertech trigger and Athlon scope. This 7mm PRC rig shows impressive accuracy.
7mm Remington Magnum vs. 7mm PRC
In this video, UltimateReloader’s Gavin Gear tests the classic belted 7mm Remington Magnum vs. the relatively new 7mm PRC. Testing is done with two hunting-type rifles shot from bipod. Gavin notes that both cartridges shoot very well, with impressive down-range energy. But he concludes that the non-belted 7mm PRC does have some advantages.
7mm Remington Magnum SAKO S20
This rifle review video features real world testing of a SAKO S20 hunting rig chambered for the 7mm Remington Magnum cartridge. The SAKO S20 is offered with multiple stock types. Here the thumbhole Hunter version with slim fore-end is featured. The testers observe that the 7mm Rem Mag factory ammo shoots very well, making the cartridge a good choice for large game.
Most Popular 7mm Cartridges
This Ron Spomer Outdoors video covers a variety of the most popular 7mm cartridges. The video covers 7mm cartridge history, ballistics, and recommendations for hunting use. Starting at the 6:45 time-mark there is a detailed ballistics comparison of the Hornady 175gr ELD-X (Extremely Low Drag eXpanding) bullet in three different chamberings: 7×57 Mauser, 7mm-08 Rem, and 7mm Remington Magnum.
7mm SAUM vs. 7mm WSM
This 17-minute video compares two modern 7mm short magnum cartridges — the 7mm SAUM (Short Action Ultra Magnum) and the 7mm WSM (Winchester Short Magnum). Both these cartridges have been adapted for F-Class Open Division use over the years. In this video, factory ammo for both cartridge types was tested with a modern chassis rifle shot prone with bipod.
7mm-08 Remington
The 7mm-08 Rem is a popular cartridge derived from the .308 Winchester necked down to 7mm. In 1980, Remington Arms popularized the cartridge by applying its own name and offering it as a chambering for their Model 788 and Model 700 rifles. Of cartridges derived from the original .308 Win, the 7mm-08 is the second most popular after the .243 Winchester.
Other than neck diameter, the 7mm-08 is virtually the same dimensionally as the .308 Win. But when you compare heavy bullets, grain for grain, the 7mm-08 offers better ballistics. Thus a 168-grainer fired from a 7mm-08 has less drop and less windage than a 168gr bullet fired from a .308 Win. The 7mm-08 enjoys most of the advantages of the .308 (inherent accuracy, long barrel life, great terminal performance) while offering better ballistics grain for grain. These qualities make the 7mm-08 a very popular deer-hunting round.
7mm Multi-Cartridge Comparison
Do you want a 7mm rifle, but haven’t chosen a cartridge yet? This lengthy 30-minute Ron Spomer video looks at a host of 7mm cartridge types. There is special emphasis with comparison data for the 7mm-08, 7mm Rem Magnum, and 28 Nosler (see 19:40 time-mark). Ron explains how to efficiently zero a rifle with these 7mm cartridges and how hunters can evaluate Maximum Point Blank Range (MPBR).

Progressive reloading presses offer shooters speed and efficiency in producing custom-tailored rifle and pistol ammunition. However, there is a wide choice of Progressive Presses and a bewildering array of options to consider. In this video, the 6.5 Guys and UltimateReloader.com’s Gavin Gear provide an overview of the leading Progressive Presses on the market along with key considerations for precision rifle shooters. If you are considering getting a Progessive for rifle ammo reloading, you should watch this informative, 25-minute video.
10 Tips for Reloading Rifle Ammo on a Progressive Press:
1. Make sure the brass is very clean. Don’t mix old range pick-up brass with newer brass.
2. Apply a thin, spray lube to all cases before the sizing/loading cycle.
3. Consider priming your brass separately (with a hand or bench tool) before the operation. Then inspect the primers before loading powder and bullets.
4. Always wear eye protection when loading with the Progressive, particularly if you are priming cases.
5. With masking tape, mark the powder measure/dropper with the powder type and cartridge charge weight. Check the charge mass multiple times (see below).
6. Cycle a few cases, sizing and adding powder but NOT seating bullets. Weigh the powder charges to ensure the powder measure is dispensing the correct charge. Sometimes this will change a couple tenths as it “settles down” after the first few charges.
7. Check the brass for shoulder bump and bullet seating depth carefully for the first few rounds, then check again periodically.
8. Try to maintain a steady pace and operate the handle the same way every time.
9. Visually inspect the powder charge in each case (before bullet seating), and use a lock-out die if your Progressive Press has enough stations.
10. Never, ever mix pistol and rifle powders! If you have previously loaded pistol ammo with your Progressive, make sure ALL the powder (every flake and kernel) is removed from all parts of the powder-dropping system before you add rifle powder.

The Bergara B14-R is a high-quality, accurate .22 LR rimfire bolt-action rifle. The rifle’s accuracy and functionality make it a good choice for NRL22 competition. And with stock geometry and ergonomics that duplicate a full-size centerfire rifle, the Bergara B14-R is also an excellent choice for cross-training. By training with a rimfire rifle, you can get essential “trigger time” while saving money. Good centerfire ammo can cost $1.50 per round or more. Decent rimfire ammo can be found for $6.00 per 50rd box. That’s just 12 cents per round.
Click above photo to load full-screen high-rez image.
To find out how well the Bergara B14-R can perform, Gavin Gear of UltimateReloader.com recently tested a B14-R (carbon-covered barrel version) at his private range. Using a variety of Lapua and SK Ammo, this rig delivered impressive results. Watch this video to see the B14-R in action.
“The B14-R is a great shooter, and for me it felt very familiar. Just like shooting one of my centerfire match guns, but without all of the recoil!” — Gavin Gear
Gavin reports: “At the 2020 SHOT Show, Bergara announced the B14-R trainer. The concept? Take the B14 HMR series centerfire rifle formula, and adapt it for rimfire. The result is a .22 LR rifle you can shoot all day long without wearing out your arm or your wallet! It looks/feels like a centerfire long-range precision rifle. And that’s what makes this rifle a GREAT training platform for serious long-range shooters.”
The B14-R comes with a 18″-long 1:16″-twist threaded barrel. The single-stack .22 LR magazine is the same size as a short action AICS mag. The Bergara B14-R shares Rem 700 specs, so it is compatible with Rem 700 stocks and aftermarket triggers. Weight with standard barrel is 9.2 pounds without optics, or 8.1 pounds for the carbon version seen here. MSRP for basic version is $1150.00 and street price is $950.00.
Gavin told us: “I couldn’t wait to get the B14-R out to my new 50-yard ridgeline range to see how it would perform with premium .22 LR ammunition. Once I shot this rifle suppressed, I didn’t want to take off the can. The 18″ barrel really works well with the SilcencerCo suppressor to help keep the overall length reasonable, and balance is spot-on.” NOTE: This rifle has the optional carbon-covered barrel.
As tested, the rifle was equipped with these components:
Athlon Midas TAC 6-14x50mm FFP Scope with MK Machine lever, Lone Star bubble level SilencerCo Omega 300 Suppressor with 1/2×28 direct thread mount Harris S-BRM 6″-9″ Bipod with aftermarket swivel tension lever
Outstanding Accuracy with Lapua and SK .22 LR Ammo
Remarkable accuracy for a factory rifle earned this Bergara its Sunday GunDay selection. Shooting with bipod and rear sandbag, Gavin was able to achieve multiple, sub-half-inch groups at 50 yards. The best group shot with SK Match ammo was a remarkable 0.22″ as measured by Ballistic-X software (see below). That’s an impressive 0.42 MOA at 50 yards. If you watch the video above, starting at 14:40 time-mark, you can watch Gavin shoot that 0.22″ group.
Here are two more groups, both under 0.5″ at 50 yards. Lapua Center-X on left, SK Match on right. Gavin says that “with good conditions, 0.35″ 5-shot groups at 50 yards are easily attainable.”
B14-R Trigger Tested with TriggerScan TS-11
Gavin tested the Bergara’s trigger with the TriggerScan TS-11 from DVORAK Instruments, a very sophisticated, high-tech device. Gavin states: “This trigger works well, and mine was adjustable down to just over 2-lb peak force for pull weight. I ran a 3-scan pass on the B14-R trigger with the pull weight set to minimum [barely over 2 pounds].”
Gavin notes: “You can see how consistent this trigger is by how well the scan graph plots overlap! This trigger is great for an out-of-the-box rifle like this, and it’s great to know that I can always swap out triggers and use the same exact Remington 700-compatible trigger that I’m running in my match guns.”
Gavin Gear’s Closing Thoughts — More to Come
The Bergara B14-R rimfire trainer has been a great rifle to shoot and has exceeded my expectations. The B14-R feels like a full-size PRS rifle, has the same basic features, but is chambered in .22 LR. I have been amazed by the accuracy I’ve achieved with this rifle with Lapua and SK match ammunition — it’s very confidence inspiring.
This rifle feels right and shoots great. I can’t wait to get more steel targets setup, and to go deeper into calculating dope for the ammunition I will shoot with this rifle. Perhaps I’ll think about competing in an NRL22 match at some point. If you are looking for a rimfire trainer, look at the Bergara B14-R for sure. It checks all of my boxes for this type of rifle!

Giraud Power Case Trimmer — Full Review by Erik Cortina
In this video, Erik Cortina of CortinaPrecision.com offers some very clever and useful tips that will help you get the most from your Giraud powered case trimmer. The Giraud trimmer is very precise. When set up correctly, it can trim brass with amazing consistency.
In the video, Erik trims 5 pieces of brass in 15 seconds (6:32 mark). He then measures all five with precision calipers (7:00-8:08). All lengths are exact within .0005 (half a thousandth). Erik notes that the Giraud trimmer indexes off the case shoulder. As long as you have fire-formed brass with consistent base-to-shoulder dimensions, you should get very consistent trim lengths.
Lyman Powered Case Trimmer Review
The Lyman Case Trim Xpress is an efficient, precise unit that allows easy adjustment of trim length with a click-adjustable collar. The trimmer comes with a set of cartridge-specific bushings that index off the case shoulder. One nice feature is a variable speed control. For the price, $146.20 on Amazon, this trimmer delivers excellent performance. To see more details, check out F-Class John’s video review of the Lyman Case Trim Xpress which shows set-up and operation.

Area 419 offers the impressive ZERO reloading press, a 9-station turret press with some very unique features. This press was designed to be the most precise turret ever created. As tested by Gavin Gear of UltimateReloader.com, the ZERO turret press delivered very impressive shoulder-bump consistency and ultra-low seated bullet run-out (about +/- 0.0005″). The numbers were as good as you can get from a quality single-stage press, so Area 419 did some impressive engineering. We would expect that, as this is an expensive product — MSRP is $1275.00. SEE FULL REVIEW on UltimateReloader.com.
The ZERO turret press lets you install up to nine (9) different reloading dies in the large top turret, which revolves around a central axis. But unlike most turret presses, the ZERO doesn’t have flex or wobble when you’re loading. This is because Area 419 includes a clever system for locking the turret in position after you’ve selected the die from your array. Area 419 also uses a unique system for securing shell-holders (see video at 12:00). This, likewise, adds to the precision of the press.
In the video above, you can see how the turret is secured with a “wedge clamp”. By loosening the wedge clamp you can index the press easily to any station. Then, when you have selected your die, you tighten the wedge clamp again. You can see this important procedure at 13:20 – 13:35 timemark in the video.
ZERO Turret Press Has Very Smooth Operation
Gavin observed that this ZERO turret is both smooth and very precise, thanks to smart engineering and the use of multiple bearings. Area 419 describes the design features:
— Turret (zero-slop) eliminates variability induced when removing and resetting dies
— The turret head holds nine 7/8×14-threaded dies (1-1/4 thread in future)
— Available ram-stroke here is 4.4″, allowing use of very tall cartridge types.
— Adjustable/interchangeable handle setup for maximizing leverage/feel based on operation
— Internally contained primer-catch system, slide-out drawer
Important Features of ZERO Turret Press
1. Press frame: 6061 Aluminum, clear anodized
2. Wedge clamp (locks turret into indexed position)
3. Turret (7075 aluminum and steel construction)
4. Adjustable handle with roller knob (set either left- or right-handed operation)
5. Bearings: Ball bearing plus roller thrust bearings for side plates
6. Ram riding in self-lubricated linear bearing
7. Spent primer catcher drawer
Milled from American billet aluminum and stainless steel, this press employs 14 bearings, including a self-lubricating linear sleeve bearing for the precision-ground 1.25″ ram. The linkage system also glides on bearings providing smooth operation with near-ZERO slop. The oversized ram features a 0.75″-diameter steel arm and ZERO-friction knob. The turret system is located with an oversized ball-detent system and secured using an over-sized, custom-made ZERO-point pull-stud. Locking the turret after indexing require only a half-turn of the supplied T-handle (see photo above). When indexing the turret, repeatability variance of the system should be less than .0005″.
The opening in the press will allow for sizing and seating of cases up to .338 Lapua Magnum, and will accept standard 7/8″ dies and standard shellholders. NOTE: Area 419 now offers a shellholder system with six precision headspace inserts that allow you to precisely tune shoulder bump when using the ZERO press: “With the new ZERO Modular Shellholder System you can set up your shellholder to your die and have more consistency, more repeatability, and less hassle.”
SUMMARY — Impressive Press Delivers Precise Results
Gavin Gear was very impressed with Area 419’s new Zero Press, which he said offers the precision of a quality single-stage with the versatility of a turret: “There will always be people that prefer a traditional single-stage. Where the ZERO will be compelling is to those who want the precision of a single-stage without the need to screw dies in and out. Leaving your dies set can have benefits for precision as well — everything comes back to the ‘same place’ when dies are indexed into position. Screwing dies in and out can impose variation, and variation is the enemy of the ‘white lab coat shooter’. I plan on testing the ZERO press with ultra-high-end dies, and custom dies that I ream to my own specifications. I’m thinking that will show the true potential of this press!”

The RCBS Lock-Out Die can also be used with some Dillon and Hornady progressive presses.
If you load pistol or rifle ammo with a progressive press, we strongly recommend you get a Lock-Out Die from RCBS. This unique reloading die will prevent your progressive press from advancing if the dispensed powder charge is more or less than about 0.3 grains too high or too low. The Lock-Out Die really works. Your Editor uses it on his RCBS 2000 progressive press. I can affirm that a Lock-Out Die has “saved my bacon” a half-dozen times over the years when there was an over-charge (which could cause a Kaboom) or a low charge (which could cause a squib load).
The Lock-Out Die works by using a central die detection rod that sets its vertical position based on the height of the powder column in the case. Through an ingenious design, if the powder column height is too low or too high, the rod locks in place as you start to pull the press handle. This halts the press before the ram can lift and the cartridge plate can advance. Unlike a beeping alarm system (which can be ignored or defeated), the Lock-Out Die physically stops the movement of the press ram and prevents a bullet being seated in the “problem” case.
It takes a bit of tweaking to get the Lock-Out Die detection rod setting just right, but once it is correctly positioned, the Lock-Out Die works smoothly in the background. The Lock-Out Die won’t interfere with the loading process unless it detects a high or low charge — and then it positively stops the progressive loading cycle.
While crafted for use in RCBS progressive presses, the RCBS Lock-Out Die can also be used on a Dillon XL Progressive (see video below) or Hornady Lock-N-Load progressive — though it does take up one station which could otherwise be used for a final crimp die (after the seating die). The RCBS 2000 has one more station than a Dillon 550/650, so it’s an ideal platform for using the Lock-Out Die.

For the very first day of 2023 we present a precision rifle built with a relatively new cartridge — the 6GT. Developed by George Gardner of G.A. Precision and Tom Jacobs of Vapor Trail Bullets, the 6GT was designed to have the efficiency of a 6mm Dasher without the need for case forming. It was also designed with a longer case body so it feeds better from magazines. Even with the added capacity, the 6GT is still very efficient, and can achieve good velocities with less powder than a 6mm Creedmoor.
Today’s Sunday Gunday feature rifle was smithed and tested by Gavin Gear of UltimateReloader.com. Gavin did all the gunsmithing — chambering the barrel, fitting the muzzle brake, and even laser engraving the barrel. In building this 6GT rifle, Gavin used top-tier components: BAT TR action, Krieger 28″ 1:7.5″-twist 4-groove 6mm barrel, TriggerTech Diamond Rem 700-compatible trigger, and Area 419 Hellfire Muzzle Brake. The barreled action was then fitted in a handsome and rugged MDT ACC Chassis. On top is a Zero Tech 4.5-27×50mm FFP Trace Advanced scope in 30mm Hawkins Precision high rings.
We recommend you watch the video above — it covers the rifle build, load development, and then features some remarkable shooting sequences across snowy hills in the Pacific Northwest. Gavin’s team actually used a drone to capture overhead footage of the location.
After developing a promising load with Berger 109gr LRHT bullets, Varget powder, and Alpha brass, Gavin literally headed for the hills to test his new rifle at longer ranges, shooting from bipod. His load had shot well under half-MOA at 100 yards in testing so he was hoping he could hit multiple steel targets positioned at 340 yards, 760 yards, and 1000 yards. Indeed he did, proving the rifle’s great accuracy and Gavin’s fine trigger-pulling skills. You can see the hits at these time points in the above video:
340 Yards — 18:15 time | 760 Yards — 19:00 time | 1000 Yards — 19:54 Time
Gavin’s 6GT Hit Highlights on Steel out to 1000 Yards
Building Gavin’s 6GT Precision Rifle
Gavin Gear did all the gunsmithing on this project, using his own Precision Matthews TL-1660 lathe for the chambering with an Alpha carbide 6GT reamer. The barrel work took about four hours total. Shown below is the reamer cutting the chamber, which was finished with a 0.170″ freebore and 0.270″ neck diameter. For other brands of brass you might want the chamber to have a larger 0.272″ neck diameter.
Chambering the Krieger barrel with Alpha carbide 6GT reamer, 0.170” freebore, .270″ neck diameter.
This project when smoothly, with Gavin able to install the barreled action in the MDT Chassis and fit the buttstock in an hour or so. So total build time was about five hours. One nice “finishing touch” on the project was laser engraving the 28″ Krieger barrel — a process you can see in the video below.
Laser engraving of Krieger 28″ barrel.
About the 6GT — Sort of a 6 Dasher on Steroids
6GT Cartridge Design Features
The 6GT was designed to have an optimal length and capacity for mag-fed PRS/NRL tactical rifles. The 6GT is longer than a 6mmBR and 6 Dasher, but shorter than a 6mm Creedmoor and 6.5×47 Lapua. That gives the 6GT ample case body length to feed reliably from a magazine, while the case capacity is sufficient to run popular powders at reasonable pressures. It has a 35-degree shoulder angle.
On paper the 6GT seemed like the perfect cartridge for PRS- and NRL-style centerfire competition. It has the low recoil of a 6 Dasher, with good feeding and mag compatibility. With the 6GT, a competitor can push 6mm 105gr bullets at 3000+ FPS or run heavier bullets at ~2950 FPS. With this 28″ Krieger barrel, Gavin actually achieved 3004 FPS running 109gr Bergers.
Gavin started with quality Alpha Munitions brass. The cases were then annealed with an AMP Annealer and trimmed to length with a Henderson powered trimmer (see video below). After sizing with a Forster Co-Ax press, Federal SR Primers were seated using a Primal Rights competition seater. Next the powder was measured with an A&D FX120i force restoration scale. Finally, the Berger 109gr LR Hybrid Target bullets were seated with a Forster Micrometer die, again using the smooth Forster Co-Ax press.
Initial Load Testing with Berger and Hornady Projectiles
Before it got cold and snowy, Gavin did load development, shooting from a bench with a Sinclair front rest. The Krieger cut-rifled barrel was accurate right from the start and Hodgdon Varget powder proved to be a very good choice for the 6GT.
Gavin’s 6GT boasts a MDT ACC short action chassis with SRS-X Elite buttstock, vertical grip, and MDT CKYE-POD Bipod.
Gavin did initial load testing with both Hornady 110gr A-Tip Match and Berger 109gr Long Range Hybrid Target bullets. The Berger 109gr LRHT bullets were the most promising. A variety of charge weights were tested, with Gavin settling on 34.6 grains of Varget. This delivered fine accuracy with a 3004 FPS muzzle velocity. Group size measurements with this load are shown in the chart. At 100 yards, four three-shot groups averaged 0.361 MOA, and the rifle produced a nice 0.387 MOA (0.405″) five-shot group.

Coming Soon — Ultimate Reloader Rifles Business
Gavin Gear is in the process of opening his own gunsmithing business. He will be offering a variety of custom-built rifles for multiple disciplines — hunting, PRS/NRL, ELR, and other competitive disciplines. Gavin explains: “Ultimate Reloader is gearing up to do custom rifle work for the general public starting (hopefully) in Spring 2022. We will most likely start with complete custom rifle builds using parts from our inventory. We will focus on high-end, bolt-action rifle builds and gunsmithing, primarily Remington 700 and clones. We will entertain limited gunsmithing work outside of complete builds (i.e. chambering, muzzle threading).
UltimateReloader.com offers some of the most thorough firearms and reloading tool tests on the internet. And UltimateReloader’s YouTube Channel has hundreds of great videos that showcase reloading tools, accurate firearms, precision optics, gunsmithing methods, and top-tier reloading components. For today’s Saturday at the Movies feature, we showcase six great videos recently created by Gavin Gear and his UltimateReloader team. These videos highlight a superb Long-Range Target Camera, the remarkable AMP Press, the new Hornady PRC cartridges, and other interesting topics. On this final day of 2022, enjoy our Saturday Video Showcase.
With the high price of centerfire powders, bullets, and brass, everyone should have an accurate .22 LR rimfire rifle for marksmanship training and competition at 25 to 200 yards. In this video, Ultimate Reloader’s Gavin Gear tests the impressive Anschutz 54.18 BR50-U7 match rifle using a quality Sinclair Int’l front rest. Anschutz offers several versions of the 54.18 and BR-50. There are two barreled actions available: 20″ threaded and 25.9″ non-threaded. Gavin tested the 20″ threaded model with the U7 stock. In this video, Gavin tested the trigger with a sophisticated TriggerScan TS-11. The trigger was superbly repeatable at a measured 3.8 ounces. Gavin also did a bore examination. He then tested the Anschutz with a variety of premium ammo. In this rifle, Lapua Midas+ producing the smallest groups. FULL STORY HERE.
This video features the impressive, high-tech AMP Bullet Seating Press. The AMP Press combines a motor driven ram, a distance sensor, and a load cell to deliver extremely accurate and precise force/distance bullet seating measurements. The AMP Press offers unrivaled consistency in the bullet seating process. And as the AMP Press is linked to a computer, seating data can be stored and you can chart variations in seating resistance. A wealth of precise data is collected during the bullet seating process. This helps you optimize your brass prep and annealing for the best, most consistent results. FULL STORY HERE.
Past 400 yards or so, it can be difficult to see bullet holes on paper, even with spotting scopes. That’s why we recommend a high-quality wireless target camera. The best long-range target cameras on the market are produced by Longshot Camera Systems. The Longshot Target Cam provides a live WiFi camera feed. This comes back to your shooting station and you can view the image with a laptop or mobile device. You don’t need internet coverage and no separate tall antennas are required. Simply place the camera unit next to your target and the receiver unit close to your rifle or bench. The Longshot system is completely self-contained. Longshot produces a variety of cameras starting at $449.00 for the LongShot Marksman. We recommend the $899.00 LR-3 unit which works out to two miles! In this video Gavin Gear of UltimateReloader tests the LR-3 at long range. PRODUCT INFO HERE.
This video examines how muzzle brakes reduce recoil. Just how important is bore clearance for a muzzle brake? Should you have an exit diameter that’s just slightly larger than bullet diameter, or will a larger diameter work well also? Along with no brake at all (bare muzzle), Ultimate Reloader tested multiple different brake bore clearances on a 6.5 Creedmoor rifle: 0.010″ over bullet diameter, 0.020″, 0.030″, 0.050″, 0.100″, and 0.200″. The testers expected to get the best recoil reduction with the tightest fit. Surprisingly, this wasn’t quite the case.
Using all brake configurations (all bore clearances) Ultimate Reloader saw a significant reduction in recoil, almost half, as compared to a bare muzzle: “What we didn’t expect was how close together the rest of the clearances would cluster. All of the clearances that we tested had good recoil reduction.” FULL STORY HERE.
Dillon Precision continues to be the leader among progressive press makers. Dillon offers the largest variety of progressives, the most accessories, and legendary customer service. In this video, Gavin Gear of Ultimate Reloader looks at a variety of Dillon machines to help buyers decide which progressive best suits their needs. Featured Dillon progressives include: Square Deal B, Xl750, and RL1100. Along with basic press feature, Gavin shows the operation of Dillon’s automated bullet feeder and case feeder accessories. The video also provides pricing summaries with various configurations. FULL STORY HERE.
Hornady’s PRC (Precision Rifle Cartridge) family of cartridges are becoming quite popular. The 6.5 PRC fits in a short action, while the 7mm PRC and 300 PRC both require a long action. The 7mm PRC is a long-action centerfire hunting cartridge designed to shoot 180gr bullets at 2950+ FPS. The 6.5 PRC is a good hunting cartridge that can fit a standard-length action. And, a number of top F-Open shooters are necking up the 6.5 PRC for 7mm bullets. This 7-6.5 PRC wildcat has shown excellent F-Class accuracy with a higher velocity node than the .284 Winchester. Along with these two cartridges, Hornady has a 300 PRC that can shoot the big .308-caliber bullets. In this video, Ultimate Reloader analyzes and compares each of the three PRC cartridge types.

Setting optimal bullet seating depth is very important for maximum accuracy. While some cartridges and barrels may deliver good accuracy with a wide range of bullet seating depths, other barrels may be more fussy, and may strongly prefer a specific seating depth, such as .006″ in the lands or .020″ off. To get this kind of precision, you need to know the exact position of the lands in your barrel. In addition, because barrel throats tend to move as the round count goes up, you should check the position of the lands regularly on a competition rifle.
Today’s Saturday Videos demonstrate a number of methods for finding Length to Lands in your rifle barrel. We start with the most common method — using the Hornady O.A.L. Gauge with a threaded modified case. With some practice, and a refined touch, this is actually very accurate. After this, we offer videos that have alternative methods, each with its pros and cons. You should find a method that works for you, that can achieve results within a couple thousandths for multiple measurements.
Finding Cartridge Length to Lands with O.A.L. Gauge
Probably the most common method to find length to lands is using a Hornady O.A.L. Gauge Tool with a comparator on a set of calipers. We regularly use this method with a custom modified case for our 6mmBR rifle. Using the technique described below, we can get results within .0015″ or so three out of four times. We do recommend taking multiple measurements. As explained below, be consistent and do NOT push the gray plastic rod too fast or with too much force.
During this measurement process, the modified case, with a bullet in its neck, is inserted in the chamber. Go slow, take your time. Here are FIVE TIPS that will help you get repeatable and reliable length-to-lands measurements with the Hornady O.A.L. Gauge:
1. Start with a clean chamber and clean barrel throat.
2. Make sure the modified case is fully screwed down and seated on the O.A.L. Gauge. It can sometimes unscrew a bit during repeated measurements.
3. Insert the modified case slowly and gently, but ensure the shoulder of the modified case is fully seated on the end of the chamber.
4. Push the gray plastic rod GENTLY. It is common for the bullet to be tilted a bit. You want to allow the bullet to self-center in the throat BEFORE you apply much pressure. Then tap a couple times and push until you feel resistance. Do NOT push too hard — that will jam the bullet in the lands.
5. Repeat the measurement at least 3 more times. If you follow our instructions, you should, typically, get a repeatable measurement, within 0.0015″ or so, 3 out of 4 times.
NOTE: We’ve seen some folks struggle to get repeatable measurements with this tool. In most cases, they were going too fast and pushing too hard on the gray rod, creating a hard jam.
Brownells — Using Hornady O.A.L. Gauge with Modified Case
This Brownells video shows how to use the modified (threaded) case for the cartridge your rifle shoots. Attach it to the O.A.L. Gauge, then insert a bullet into the case neck and slide the tool into the chamber. It takes a little practice to get consistent results. After getting the measurement in the barrel, you ascertain the length to lands using a Hornady Bullet Comparator attached to your calipers.
Making Your Own Modified Case — Threading the Case End
This helpful video from our friend Gavin Gear of UltimateReloader.com shows how to create a custom modified case to use with a Hornady O.A.L. Gauge. You need to drill out the primer pocket area, then tap and thread the bottom of the case.
Ultimate Reloader Shows 3 Ways to Find the Lands
This video shows three different ways to measure distance to lands. First Gavin Gear shows how to use a Hornady O.A.L. Gauge with Modified Case. The second methods shows how to use a bit of Loctite INSIDE the neck to secure a bullet. Be sure there is NO Loctite on the outside of the neck — you don’t want that in your chamber! You place the case with bullet into the chamber, then close bolt to seat the bullet. After waiting 5-10 minutes for the Loctite to set, you remove the cartridge gently. The third method (time-mark 16:50) is a Jam method using a bolt with the firing pin assembly and ejector removed (so there is no extra pressure on the case). Gavin notes: “The bullet ogive can be colored with a permanent marker if you want to indicate lands contact.”
About this third Jam method, ace F-Class shooter Erik Cortina posted: “My method is actually the last one that Travis showed. The one where you let the lands push bullet in. But it is neck tension dependent. I also put die wax in bullet ogive to prevent it from sticking in the lands. The method of seating bullet deeper and deeper until bolt closes is the Alex Wheeler method. As you said, there are a tons of ways to measure this.”
Finding Length to Lands the Speedy Way
Here is another method to find length to lands that can work with an unmounted barrel. This method is explained by Thomas “Speedy” Gonzales, a top gunsmith and ace benchrest shooter. Speedy drops a case with bullet seated into the chamber and then adjusts the seating depth with an inline seating die until there is no sticking or resistance felt. He can then adjust the true length to lands easily with his micrometer seating die. If you don’t have a modified case and do not want to partially disassemble your bolt to take measurement, you might want to use Speedy’s method.
Finding Length to Lands Using Bolt Movement — Primal Rights
This video shows how to remove the firing pin assembly in your bolt. This way the bolt can be used to advance a case with bullet smoothly into the chamber. Then the bullet seated in the case neck will move back to “first touch” contact position. Then extract the case slowly and measure.
The video host states: “Overall length gauges and modified cases tend to be close, but never as precise as we would like them to be. Here we describe how to measure the length to your lands in your rifle as precisely as possible, using a caliper and bullet comparator.” NOTE: The host says a store-bought Modified Case may not deliver that exact same length from case base to lands as your own fired case. That is true, but as long as the commercial Modified Case gives you repeatable results, you have a functional reference point which you can then use to test seating depths relative to that measurement.
Finding Length to Lands Using Bullet in Case With Split-Cut Neck
Here is a common method that requires no special tools. Simply take a fired (no primer), neck-sized case and split the necks down vertically with a Dremel. Done right, this will hold the bullet in place when you chamber the unloaded round. As the bullet touches the rifling it will move back. As the cartridge chambers, the bullet slides back into the case to give you length to lands. This is not super-accurate but it is probably good enough for finding the length to lands for a hunting rifle. The video maker explains: “No need to purchase gauges for this if you are willing to sacrifice one case. With a little time and patience you can get good results with this method.” Further Explanation.
How to Adjust Tension — Length and Number of Neck Cuts
Forum member Andris Silins, who uses this method, explains: “I made the neck cuts using a Dremel with a cut-off wheel. You can adjust tension two ways. First, you can make the cuts longer or shorter. Longer cuts = less tension. If you used only three cuts instead of four you would get more tension. The trick is to be gentle when you open and close the bolt. If you ram the bolt closed you may wedge the bullet into the lands. When you open the bolt it helps to keep a finger or two near by to guide the case out straight because the ejector wants to push it sideways.” READ MORE.
Finding the Lands with HK Rifleworks
This is another video that demonstrates how to disassemble the bolt so that the firing pin assembly and spring does not apply pressure on the empty case which would affect the bullet as it touches the lands. The video maker shows how to use a Brownells bolt disassembly tool to quickly take the bolt apart (3:20 time-mark). Once you have a repeatable measurement, you know exactly where is “first touch”. Then you can adjust your seating depth to be into the lands, or jumping the bullets. Many benchrest shooters like to load “into the lands”. PRS/NRL shooters and hunters will generally prefer to jump their bullets .0020″ or more.

The 7mm-08 Rem is a popular cartridge derived from the .308 Winchester necked down to 7mm. In 1980, Remington Arms popularized the cartridge by applying its own name and offering it as a chambering for their Model 788 and Model 700 rifles. Of cartridges derived from the original .308 Win, the 7mm-08 is the second most popular after the .243 Winchester.
If you load pistol or rifle ammo with a progressive press, we strongly recommend you get a Lock-Out Die from RCBS. This unique reloading die will prevent your progressive press from advancing if the dispensed powder charge is more or less than about 0.3 grains too high or too low. The Lock-Out Die really works. Your Editor uses it on his RCBS 2000 progressive press. I can affirm that a Lock-Out Die has “saved my bacon” a half-dozen times over the years when there was an over-charge (which could cause a Kaboom) or a low charge (which could cause a squib load).
