In this .308 Win test, 70° F ammo shot 96 FPS slower than ammo heated to 130.5° F. And the 130.5° ammunition was 145 fps faster than ammo taken right out of the freezer (at 25.5° F). That’s a huge difference…
Summer Solstice is just two weeks away, so most parts of the country will soon be encountering peak summer heat. Some ranges in the Western states have already recorded temperatures well over 100 degrees F during matches. When dealing with extreme summer heat, you should make a serious effort to keep your ammo at reasonable temperatures. When possible, keep ammo in a cooler in the shade.
Never leave boxes of ammo out in the hot sun. Even with powders advertised as “temp stable” you can see significant velocity increases when ambient temps reach 90 degrees and above. This article explains how temperature extremes (both hot and cold) can alter bullet velocities. The velocity differences between very cold ammo and very hot ammo can be very large, as this article explains.
EDITOR’s NOTE: The Sierra tester does not reveal the brand of powder tested here. Some powders are much more temp sensitive than others. Accordingly, you cannot extrapolate test results from one propellant to another. Nonetheless, it is interesting to see the actual recorded velocity shift with ammo temperature variations in a .308 Win.
Written by Sierra Chief Ballistician Tommy Todd This story originally appeared in theSierra Bullets Blog
A few weeks ago I was attending the Missouri State F-Class Match. This was a two-day event during the summer and temperatures were hot one day and hotter the next. I shot next to a gentleman who was relatively new to the sport. He was shooting a basically factory rifle and was enjoying himself with the exception that his scores were not as good as he hoped they would be and he was experiencing pressure issues with his ammunition. I noticed that he was having to force the bolt open on a couple of rounds. During a break, I visited with him and offered a couple of suggestions which helped his situation somewhat and he was able to finish the match without major issues.
He was shooting factory ammunition, which is normally loaded to upper levels of allowable pressures. While this ammunition showed no problems during “normal” testing, it was definitely showing issues during a 20-round string of fire in the temperatures we were competing in. My first suggestion was that he keep his ammunition out of the direct sun and shade it as much as possible. My second suggestion was to not close the bolt on a cartridge until he was ready to fire. He had his ammo in the direct sunlight and was chambering a round while waiting on the target to be pulled and scored which can take from a few seconds to almost a minute sometimes.
This time frame allowed the bullet and powder to absorb chamber [heat] and build pressure/velocity above normal conditions. Making my recommended changes lowered the pressures enough for the rifle and cartridge to function normally.
Testing Effects of Ammunition Temperature on Velocity and POI
After thinking about this situation, I decided to perform a test in the Sierra Bullets underground range to see what temperature changes will do to a rifle/cartridge combination. I acquired thirty consecutive .30 caliber 175 grain MatchKing bullets #2275 right off one of our bullet assembly presses and loaded them into .308 Winchester ammunition. I utilized an unnamed powder manufacturer’s product that is appropriate for the .308 Winchester cartridge. This load is not at the maximum for this cartridge, but it gives consistent velocities and accuracy for testing.
I took ten of the cartridges and placed them in a freezer to condition.
I set ten of them on my loading bench, and since it was cool and cloudy the day I performed this test I utilized a floodlight and stand to simulate ammunition being heated in the sun.
I kept track of the temperatures of the three ammunition samples with a non-contact laser thermometer.
The rifle was fired at room temperature (70 degrees) with all three sets of ammunition. I fired this test at 200 yards out of a return-to-battery machine rest. The aiming point was a leveled line drawn on a sheet of paper. I fired one group with the scope aimed at the line and then moved the aiming point across the paper from left to right for the subsequent groups.
NOTE that the velocity increased as the temperature of the ammunition did.
The ammunition from the freezer shot at 2451 fps.
The room temperature ammunition shot at 2500 fps.
The heated ammunition shot at 2596 fps.
The tune window of the particular rifle is fairly wide as is shown by the accuracy of the three pressure/velocity levels and good accuracy was achieved across the board. However, notice the point of impact shift with the third group? There is enough shift at 200 yards to cause a miss if you were shooting a target or animal at longer ranges. While the pressure and velocities changed this load was far enough from maximum that perceived over pressure issues such as flattened primer, ejector marks on the case head, or sticky extraction did not appear. If you load to maximum and then subject your ammunition to this test your results will probably be magnified in comparison.
This test showed that pressures, velocities, and point-of-impact can be affected by temperatures of your ammunition at the time of firing. It’s really not a bad idea to test in the conditions that you plan on utilizing the ammo/firearm in if at all possible. It wouldn’t be a bad idea to also test to see what condition changes do to your particular gun and ammunition combination so that you can make allowances as needed. Any personal testing along these lines should be done with caution as some powder and cartridge combination could become unsafe with relatively small changes in conditions.

Optics — Angled and Straight Spotting Scope Designs Compared
Spotting scopes come in two basic styles — straight and angled. The angled version is the most common because it can be used from all shooting positions — even prone (just rotate the spotter around its centerline). If you are spotting from a sitting or standing position, with the spotting scope on a tripod, a straight spotter may work best. That way your head/neck/torso is not bent down and you can instantly see a full view ahead just by moving your head slightly away from the lens. In this video, Gun Talk’s Kevin “KJ” Jarnagin covers the pros and cons of Straight vs. Angled spotting scopes. KJ uses Leupold SX-4 Pro Guide HD15-45x65mm spotting scopes in both straight and angled configurations.

Season 13, Episode 7: Colt Anaconda, Frankford Arsenal X-10 Progressive Press, SIG Sauer Red Dot optics
Every handloader can benefit from a turret press. This type of press features an upper rotating disk that has multiple threaded placements for dies or other tools (such as powder dispensers). There are a variety of turret presses on the market today with the remarkable Area 419 9-Station Zero Press at the top end, and the inexpensive Lee turret presses at the other end of the spectrum. In between are Lyman’s 8-station All-American turret, the Redding 7-station T-7 press, and the RCBS 6-station turret.
Today’s Saturday video showcase features notable turret presses from all the major makers. We lead off with a feature on the advanced Area 419 ZERO 9-station turret.
Area 419 ZERO 9-Station Turret Reloading Press — Without Peer
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 represents a big investment — 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.
Quick Comparison Videos — Lyman, Lee, Redding
Below we’ve included a couple quick video “shorts” which show the Lyman Turret Press and the Lee Classic 4-Hole Turret in action. After those two vertical-format videos, there is an interesting comparison between the Redding T-7 and Lyman 8-station turret press:
This video has a side-by-side comparison of the Redding T-7 and the Lyman 8-station turret press:
Lyman Brass Smith All-American 8-Station Turret Press
The Lyman Brass Smith All-American 8-station press is an impressive product introduced five years ago. In 2018, Lyman introduced a new 8-station turret press, the All American 8. The All-American 8 has become popular with handloaders. With a $253.49 street price, the 8-station Lyman is $122 cheaper than the $375.95 7-station Redding T-7. No question, that’s a significant price advantage, and we believe Lyman has grabbed sales from Redding.
Our friend Gavin Gear of UltimateReloader.com created an informative video showing press set-up and loading function. Gavin was excited to work with this beefy new turret press: “Why was this Lyman press anticipated so highly? A few reasons are: the 8-station capacity, cast iron construction, on-press priming system, ambidextrous design, and turret rear support for repeatable sizing and bullet seating.”
More Stations Provide More Reloading Options
Gavin liked having 8 stations, because this offers more flexibility. With eight stations, you can have four two-die sets, or three two-die sets plus a dedicated decapping die and a powder measure. Gavin notes: “I’ve owned many reloading presses, including 3-station, 4-station, 5-station, and 7-station variants, but I’ve never owned an 8-station press until the Brass Smith All-American 8 came to the shop. I’ll have to say… you can’t get too many stations, especially on a manually-indexed turret. I love the idea that you can leave dies on the press, and load multiple calibers/chamberings using the same turret setup.”
Redding T-7 with Creedmoor Sports Enhanced Turret Head
The Redding T-7 has long been a leading turret press for precision handloaders. It offers one more station than the other “green” turret press offered by RCBS. It has a reliable optional priming system and plenty of leverage. Recently Creedmoor Sports has released an upgraded Enhanced Press Head for the Redding T-7. This $179.95 turret top allows greater precision in case sizing and bullet seating. This UltimateReloader video covers the advantages of the new precision turret head. READ Full Report on UltimateReloader.com.
Creedmoor Sports also offers enhanced precision press heads for the RCBS Turret Press, and Lyman 8 Turret Press. Both priced at $179.95, these two enhanced heads are featured in the video below:
Redding T-7 That Has Loaded over 1 Million Rounds
Here’s something you don’t see every day — a reloading press that has loaded over 1,000,000 rounds of ammo. At the NRA Convention in Dallas in 2018, Redding showcased an old Redding T-7 Turret Press delivered to Sierra Bullets decades ago. 0ne of the very first T-7s made by Redding, this “old warrior” was used by Sierra Bullets to load over 1,000,000 rounds of ammunition in Sierra’s ballistics lab. After all that loading, Redding tested the press and, remarkably, found that it still remained “within spec”. Redding notes: “This press was subjected to real world reloading wear and stress yet remains within ‘new’ spec after this historic test”.
RCBS Six-Station Turret Press
This Editor has used an RCBS Turret Press for over 15 years. It does not have the most stations or the most sophisticated features, but it has proven very reliable over the years. I use it primarily to use with pistol sizing and seating dies. Having six stations allows me to load multiple cartridge types: 9x19mm, .357 Magnum, and .45 ACP.

He who dies with the most toys wins — right? Well Sinclair has another interesting gadget you can add to your reloading bench. The Sinclair Case Neck Sorting Tool lets you quickly sort brass by neck-wall thickness. For those who shoot “no-turn” brass, this can improve neck-tension consistency. Large variances in neck-wall thickness can cause inconsistent neck “grip” on the bullet. Generally, we’ve found that more consistent neck tension will lower ES and (usually) improve accuracy. We know some guys who shoot no-turn 6mmBR brass in competition with considerable success — but their secret is pre-sorting their brass by neck-wall thickness. Cases that are out-of-spec are set aside for sighters (or are later skim-turned).
Watch Case Neck Sorting Tool Operation in Video
How the Case Neck Sorting Tool Works
Here’s how the Sinclair tool works. Cases are rotated under an indicator tip while they are supported on a case-neck pilot and a support pin through the flash hole. The unit has a nice, wide base and low profile so it is stable in use. The tool works for .22 through .45 caliber cases and can be used on .17- and .20-caliber cases with the optional carbide alignment rod. The MIC-4 pin fits both .060 (PPC size) and .080 (standard size) flash holes. Sinclair’s Case Neck Sorting Tool can be ordered with or without a dial indicator. The basic unit without dial indicator (item item 749006612) is priced at $59.99. You can also buy the tool complete with dial indicator (item 749007129) for $89.99. IMPORTANT: This sorting tool requires caliber-specific Case Neck Pilots which must be ordered separately.
Editor’s Comment: The purpose of this Sinclair tool is rapid, high-quantity sorting of cartridge brass to ascertain significant case-neck-wall thickness variations. Consider this a rapid culling/sorting tool. If you are turning your necks, you will still need a quality ball micrometer tool to measure neck-wall thickness (to .0005) before and after neck-turning operations.

Even with high-quality brass from Lapua, Peterson, Norma, Alpha and RWS, occasionally you may find one or two cases per box which have a small flake or obstruction in the flash-hole. This will appear like a thin crescent on one side of the flash hole (see photo). You should inspect ALL new brass before loading to identify any pieces with a partially-obstructed flash hole. It’s a good idea to remove any flake or thin crescent left as an artifact of the flash-hole forming process. Because the flash-hole itself is normally centered and of the correct diameter, it is not necessary to ream the flash-hole to a larger diameter. All you really need to do is remove the small obstruction(s). This can be done quickly with inexpensive tools.
Use a Small Pin Vise to Remove Flash-Hole Obstructions
Folks have asked if there is a tool that can remove obstructions from a Lapua small, BR-sized flash hole without opening the hole size. The Lapua PPC/BR flash hole is spec’d at 1.5mm, which works out to 0.059055″. Most of the PPC/BR flash-hole uniforming tools on the market use a 1/16″ bit which is nominally 0.0625″, but these often run oversize — up to 0.066″.
If you want to just clear out any obstructions in the flash hole, without increasing the flash hole diameter, you can use an inexpensive “pin vise” with an appropriate drill bit. For $0.99 ($0.50 on sale), eHobbyTools.com sells a 1.5mm drill bit, item 79186, that matches the Lapua flash hole exactly. Other vendors offer a #53 pin vise drill bit that measures .0595″ or .060″ (depending or source). An 0.0595″ bit is close enough. You can find pin vises and these small-diameter drill bits at hobby stores.
For quite some time, Sinclair Int’l has sold a similar device for small (PPC and BR-size) flash holes. Like the 07-3081 unit for large flash holes, the 073000 Reamer for small flash holes works from the outside, so it can index off the primer pocket. It reams to .0625″, and also costs $29.99. The standard dimension for Lapua 220 Russian and 6mmBR flash holes is 1.5mm or .0590″. This tool will permit standard-size decapping rods with .0625″ tips to work without binding. However, note that both Forster and Redding normally supply .057″ decapping pins with their PPC and BR dies. So, it is NOT necessary to ream your Lapua BR/PPC flashholes, unless you prefer to do so for uniformity. It IS, however, a good idea to check BR/PPC flash holes for burrs before loading the first time.
NOTE: If you purchase either the 073081 or 073000 Sinclair Flash Hole Reamer tools, we recommend you mic the cutter tip before you process a bunch of cases. Sometimes a tip comes through that is oversize. This will ream the flash holes larger than you may intend.

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!”

A few years back, Our friend Grant Guess had a “close encounter” with a bad primer. An apparently defective primer caused part of the casehead on one of his rounds to blow out. This, in turn, allowed high pressure gas to vent through the damaged primer pocket. Take a good look, boys and girls. This is yet another very good reason to wear safety glasses … EVERY time you shoot. The cartridge was a 6.5-06, handloaded in necked-down Winchester-headstamp .270 Win brass. Grant reports:
“I had a blow-through between the primer and the primer pocket today. The action was really smoking and I got a face full of gas. This was a reasonably light charge. Thank God for safety glasses.
I should also mention that it appears there is a 3/64 hole that is halfway between the primer and the primer pocket. Like it burned a small jet hole through both of them.”
Could this happen to you? It just might. On seeing this damaged case, one of Grant’s Facebook friends, Chris D., observed: “Search the internet, you will see a lot of these pin hole ‘in the corner’ failures. Obviously Winchester has some issues with the LR primers.”
Careful Examination Reveals Apparent Primer Defect
After this incident, Grant examined the damaged case: “I [measured] the flash hole and it is not over-sized or under-sized. The primer clearly has an area where it had a defect. At [50,000 CUP], it doesn’t take much of a defect to cause issues. There was a slight bit of pucker-factor on the next shot….”

Sierra Bullets has released extensive load data for the popular 6.5 Creedmoor cartridge. This medium-sized cartridge has become one of the most popular chamberings for tactical and PRS shooters. The 6.5 Creedmoor combines excellent accuracy, good mag-feeding, good barrel life, moderate recoil, and reasonable component cost. That’s why this cartridge has caught on quickly, and is now one of the most popular chamberings in factory rifles.
Developed in 2007 by Dennis DeMille and Dave Emary, the 6.5 Creedmoor is a shortened and improved 30 TC cartridge case that was inspired by the .308 Winchester design. This short action design was created to maximize case capacity and a wide range of loading lengths, while still fitting in standard short action magazines. With the correct twist barrel, the versatile 6.5 Creedmoor can take advantage of the wide range of bullet weights available in 6.5 mm (i.e. .264 caliber). Reloaders should keep in mind that the 6.5 Creedmoor works best with medium to medium-slow powders such as H4350, Varget, Win 760, and RE-17. The light recoil and adaptability of the efficient 6.5 Creedmoor cartridge has already proven itself in high power, precision rifle series and benchrest competitions. Couple that with respectable barrel life and its intrinsic accuracy potential and you have a recipe for success which should insure its legacy for decades to come.
Here are three tables from the Sierra Bullets Reloading Manual (5th Edition). IMPORTANT — This is just a sample!! Sierra has load data for many other 6.5mm bullet types, including FB, Spitzer, SBT, HPBT, and Tipped MK from 85 grains to 142 grains. To view ALL 6.5 Creedmoor DATA, CLICK HERE.

The shape of powder grains has a profound effect on the performance of the powder charge, as it concerns both pressure and velocity. There are multiple powder shapes including flake, ball, and extruded or “stick” (both solid and perforated).
So how does powder grain shape affect pressure and muzzle velocity?
In general, it can be said that powder that burns progressively achieves a desired muzzle velocity at lower maximum pressure than a powder that burns neutrally, not to mention a degressive powder. As grain size increases, the maximum pressure moves towards the muzzle, also increasing muzzle blast. Muzzle velocity and pressure can be adjusted by means of the amount of powder or loading density, i.e. the relationship between the powder mass and the volume available to it. As the loading density increases, maximum pressure grows.
All Vihtavuori reloading powders are of the cylindrical, single-perforated extruded stick type. The differences in burning rate between the powders depend on the size of the grain, the wall thickness of the cylinder, the surface coating and the composition. Cylindrical extruded powders can also have multi-perforated grains. The most common types are the 7- and 19-perforated varieties. A multi-perforated powder grain is naturally of a much larger size than one with a single perforation, and is typically used for large caliber ammunition.
Other types of powder grain shapes include sphere or ball, and flake. The ball grains are typically used in automatic firearms but also in rifles and handguns. The ball grain is less costly to produce, as it is not pressed into shape like cylindrical grains. Flake shaped grains are typically used in shotgun loadings.
Web thickness in gunpowder terminology means the minimum distance that the combustion zones can travel within the powder grain without encountering each other. In spherical powders, this distance is the diameter of the “ball”; in flake powder it is the thickness of the flake; and in multi-perforated extruded powders it is the minimum distance (i.e. wall thickness) between the perforations.
The burning rate of powder composed of grains without any perforations or surface treatment is related to the surface area of the grain available for burning at any given pressure level. The change in the surface area that is burning during combustion is described by a so-called form function. If the surface area increases, the form function does likewise and its behavior is termed progressive. If the form function decreases, its behavior is said to be degressive. If the flame area remains constant throughout the combustion process, we describe it as “neutral” behavior.
The cylindrical, perforated powders are progressive; the burning rate increases as the surface area increases, and the pressure builds up slower, increasing until it reaches its peak and then collapses. Flake and ball grains are degressive; the total powder surface area and pressure are at their peak at ignition, decreasing as the combustion progresses.
In the ELR game, particularly the King of 2 Miles (KO2M), it’s “go big or go home”. The top shooters run large-capacity cartridges that push large-caliber, ultra-high BC bullets at very high velocities. Bullets launched by cartridges such as the .416 Barrett can sustain supersonic velocities at Extreme Long Ranges — and that’s what it takes to win. The .416 Barrett can launch a 550-grain solid bullet at 3000+ FPS.

2018 and 2019 Kings of 2 Miles Loaded on RCBS Presses
So how do you load jumbo cartridges such as the .416 Barrett? It takes a big, heavy, super-strong reloading press. We’ve learned that two recent King of 2 Miles champions, Paul Phillips (2019) and Robert Brantley (2018) both loaded their KO2M ammo on RCBS AmmoMaster .50 BMG presses. Phillips loaded .416 Barrett ammo, while Brantley loaded a similar .416 MCS cartridge.
In 2018, Robert Brantley topped the field using his custom .416 MCS cartridge. Then in 2019, Paul Phillips won the K02M competition shooting a .416 Barrett, with Brantley a close second. Both Phillips and Brantley use the RCBS AmmoMaster .50 BMG single stage press kit and RCBS .416 Barrett dies to hand-load for extreme long-range. “My ammo has been much more consistent after switching to the RCBS press and dies,” remarked Phillips, who runs the Global Precision Group. Brantley said he uses RCBS products for most of his reloading needs — from the dies and AmmoMaster, to the ChargeMaster and Brass Boss. His custom .416 MCS loads launch a 550-grain bullet more than 3,100 fps.
Loading with RCBS AmmoMaster .50 BMG Press
This video shows reloading with the RCBS AmmoMaster .50 BMG press. While this video shows .50 BMG cases being loaded, the principles are the same for loading the .416 Barrett cartridge or other big rounds. Big cases need big presses!

In years past, the U.S. Army Marksmanship Unit published weekly reloading “how-to” article on the USAMU Facebook page. Here is a very informative USAMU article the subject of case lubrication. Tasked with producing thousands of rounds of ammo for team members, the USAMU’s reloading staff has developed very efficient procedures for lubricating large quantities of cases. This article reveals the USAMU’s clever “big-batch” lube methods. For other helpful hand-loading tips, visit the USAMU Facebook page on upcoming Wednesdays.
Rapid, High-Volume Case Lubrication
Today’s topic covers methods for quickly applying spray lube to cartridge cases prior to sizing. A typical order for this shop may be 25,000 rounds, so [speeding up] the lubrication process can be a real time-saver. While your ammunition lots probably aren’t this large, the efficient methods discussed here may help save a considerable amount of time over your handloading career. Our case lubrication rates range from 1500-1600 cases per hour, to 2400-2500 cases per hour, depending on caliber.
This shop uses virgin brass, whereas most home handloaders use fired brass, which necessitates some small changes at times. These will be discussed as they arise. Begin with fired brass that has been tumbled clean.
Ensure as much tumbling media as possible is removed from the brass, as when it gets into a size die, it can dent cases significantly. This is a good time to round out dents in the case mouths using a tapered tool to prevent damage from the decapping stem.
First, dump the clean cases into a large box or reloading bin. Shake the bin back and forth so that many cases are oriented with the mouths up. Next, pick up as many cases as is convenient with the mouths “up”, from natural clusters of correctly-oriented cases. With 7.62mm-size cases, this is usually 3-4, and with 5.56mm cases, this can be up to 8-10. Place the cases into the rack slots, mouth-up. Doing this in groups rather than singly saves considerable time. Once these clusters have been depleted, it will be time to re-shake the bin to orient more cases “up.”.
This photo shows a case lubrication rack made by a USAMU staffer.
Naturally, adjust the spacing to best fit the calibers you reload. We have found this size … convenient for handling through the various phases of case lubrication/transfer to progressive case feeders for processing. Note that the 1/2-inch angle does not cover much of the critical case area at the base, just forward of the extractor groove, where most re-sizing force will be exerted. As the USAMU uses virgin brass, less lubrication is required for our brass than would be needed for Full Length (FL) sizing of previously-fired brass.
NOTE: The amount applied using our rack is easily enough for our purpose. If using fired brass, be sure to adequately lube this base area to avoid having cases stick in the full-length sizing die.
Using a spray lube, coat the cases adequately, but not excessively, from all sides. Be sure to get some lube into the case mouths/necks, in order to reduce expander ball drag and case stretching/headspace changes. The spray lube this shop uses does not harm primers or powder, and does not require tumbling to remove after lubing.*
Take a close look at the photo above. The USAMU shop uses a common kitchen turntable, which allows the rack to be rotated easily. We place this in a custom-made box which prevents over-spray on to floors and walls.
Angled Box Method for Smaller Cases to be Neck-Sized
A refinement of the above method which especially speeds processing of 5.56x45mm cases is as follows. A small cardboard box which holds about 100 cases is fitted with an angled “floor” secured by tape. With the smaller 5.56mm cases, usually about 8-10 cases per handful can be picked up, already correctly-oriented, and placed into the box together. This prevents having to place them into the rack slots, saving time.
HOWEVER, note that this does not allow nearly as much lube access to the case bodies as does the rack. For our purposes — neck-sizing and setting neck tension on new brass, this works well. If using this procedure with fired brass, take steps to ensure adequate lube to prevent stuck cases.
As always, we hope this will help our fellow handloaders. Good luck, and good shooting!
*A two-part test performed here involved spraying primed cases heavily, while getting more lube into the case mouth/body than even a careless handloader would likely apply. The second part of the test involved literally spraying considerable quantities of the lube directly into the cases, drenching the primers. After a several-day wait to allow the lube to penetrate the primers, they were then fired in a test barrel. All fired normally; no unusual reports were noted. This bolstered confidence that normal amounts of the lube would not adversely affect our ammunition, and we have been pleased with the results over several years.

Do you own an RCBS electronic powder dispenser? If you do, take the time to watch this ChargeMaster Tuning video from 8541 Tactical. This nine-minute video demonstrates how to re-program your ChargeMaster to “tune” the dispensing process. The video shows the exact programming procedures to follow, step-by-step. Some folks want a faster powder flow — others tune their machines for a more reliable drop (with fewer over-runs). One cheap and popular modification is to insert a 1″-long section of a McDonald’s plastic straw in the ChargeMaster’s silver dispensing tube. This works surprisingly well to smooth kernel drop and prevent “clumping” that can cause an over-charge. The McDonald’s straw MOD is demonstrated in this video, starting at the 6:22 mark.
Large-Diameter Dispensing Tube Mod
Many folks have had success with the McDonald’s straw modification demonstrated in the above video. However, some folks would like to get even better flow performance (with virtually no clumping). Forum Member Frank B. has come up with a new option using a brass hose fitting with a large outside diameter. The hose fitting (with tape wrapped around the barbed nose section) is placed inside the RCBS dispensing tube (have some kind of wrap — you don’t want metal-on-metal). Here’s how the unit looks installed:
Frank tells us: “I have found a cure for the over-throw problem. It is a simple 1/4″ barbed hose nipple. I wrapped a couple layers of tape around the barbed end for a snug fit. With this in place, I have thrown 100+ charges of Varget without a single overthrow. The ID of the barbed end needs to be approximately 3/16″ to feed a steady flow. This works because of the larger ID at the drop.”
Frank adds: “You can see in the photo that the powder is not stacking up. You can watch it drop one grain at a time. Hope this will take the aggravation out of your case charging.” For best performance with this brass fitting MOD, we recommend de-burring and smoothing out the front edge of the brass fitting over which the kernels drop.

Summer Solstice is just two weeks away, so most parts of the country will soon be encountering peak summer heat. Some ranges in the Western states have already recorded temperatures well over 100 degrees F during matches. When dealing with extreme summer heat, you should make a serious effort to keep your ammo at reasonable temperatures. When possible, keep ammo in a cooler in the shade.
