Precision Reloading Tips from Sinclair Int’l Experts

Froggy Reloading Bench

cartridge reloadingA while back, Sinclair International’s Reloading Press Blog featured a “round-table” discussion of reloading techniques. Sinclair’s team of tech staffers were asked: “What do you feel is the one-most crucial step in precision reloading?”

Here are their responses (along with comments from our Editors):

Phil Hoham: “I feel that when working up a load do not go too high or too low in your powder charge. Stay away from ‘suggested loads’ you hear at the range, or on the internet. Always be sure to use a published reloading manual that presents not only minimums and maximums, but also pressure, velocity, and a proper range of powders used. Do not get distracted in the reloading process, and remain focused at all times during each step involved.” Some loads presented on the Internet are OK as a starting point, but it is absolutely critical to understand that pressure maximums will vary considerably from one rifle to another (of the same chambering). For example, one 6mmBR rifle shooting 105gr bullets can max out with 30.0 grains of Varget powder, while another rifle, with the same chamber dimensions, but a different barrel, could tolerate (and perform better) with half a grain more powder. You need to adjust recommended loads to your particular rifle and barrel.

Pete Petros: “This could be a very broad topic, but if I were to pick one, it would be making sure to pay close attention, and weigh each and every powder charge to ensure that each load is exact and consistent. This is important not only for accuracy, but also for safety reasons.” If you’re shooting beyond 200 yards, it is critical to weigh your loads with an accurate scale or automated system such as the AutoTrickler V3/V4. Loads that are uniform (within a few kernels) will exhibit lower Extreme Spread and Standard Deviation. And remember, even if you stick with the same powder, when you get a new powder lot, you may have to adjust your load quite a bit. For example, .308 Palma shooters have learned they may need to adjust Varget loads by up to a full grain from one lot of Varget to the next.

Ron Dague: “I feel that the most important step(s) in reloading for accuracy are in the initial case prep. Uniforming the primer pocket to the same depth to ensure consistency in primer seating is a crucial step. Additionally de-burring the flash holes, each in the same way to clean up and chamfer the inside is important. It ensures that the ignition from the primer is uniform and flows out in the same consistent pattern. Doing so will create uniform powder ignition and tighten up your velocity Extreme Spread.” With some brands of brass, primer pocket uniforming and flash-hole deburring is useful. However, with the best Lapua, Norma, and RWS brass it may be unnecessary, or worse, counter-productive. So long as your Lapua brass flash-holes are not obstructed or smaller than spec, it may be best to leave them alone. This is particularly true with the small flash holes in 220 Russian, 6BR, and 6.5×47 cases. MOST of the flash-hole reaming tools on the market have cutting bits that vary in size because of manufacturing tolerances. We’ve found tools with an advertised diameter of .0625″ (1/16″) that actually cut an 0.068″ hole. In addition, we are wary of flash-hole deburring tools that cut an aggressive inside chamfer on the flash-holes. The reason is that it is very difficult to control the amount of chamfer precisely, even with tools that have a depth stop.

Rod Green: “I feel that bullet seating is the most important step. If you had focused on making sure all prior steps (case prep, powder charge, etc.) of the process have been carefully taken to ensure uniformity, bullet seating is the last step, and can mean all the difference in the world in terms of consistency. Making sure that the bullet is seated to the same depth each time, and time is taken to ensure that true aligned seating can make the load.”

Bullet seating arbor press

Bob Blaine: “I agree with Rod. I strongly feel that consistent bullet seating depth is the most important step in creating the most accurate hand loads. I have seen the results in both my bench and long range rifles. Taking the time to ensure exactness in the seating process is by far, the number one most important step in my book.” Agreed. When loading match ammo, after bullet seating, we check every loaded round for base of case to ogive length. If it varies by more than 3 thousandths, that round is segregated or we attempt to re-seat the bullet. We measure base of case to bullet ogive with a comparator mounted on one jaw of our calipers. You may have to pre-sort your bullets to hold the case-base to ogive measurement (of loaded rounds) within .003″.

AR Platform Video Series from Brownells — Watch and Learn

Brownelss tech tip video AR15 ar platform rifle gunsmithing

Do you own or shoot an AR-platform “black rifle”? Then you know these rifles run dirty, and have some unusual maintenance requirements. On the other hand, the AR “Modern Sporting Rifle” is fun and versatile with a vast range of options among buttstocks, barrels, handguards, and grips. You can assemble a simple 16″ barrel .223 Rem rig for home defense, or build a long-barreled 6mm ARC rifle with bag-rider buttstock and high-magnification optic for long range target work. The choice is up to you.

To help with your black rifle journey, here are four helpful videos from Brownells. These will help ensure your AR rifle cycles reliably and runs longer, with reduced wear. Brownells also explains how to choose the optimal barrel twist rate. CLICK HERE to order AR parts, accessories, and ammo from Brownells.

AR Bolt/Bolt Carrier Lubrication — Smarter Methods

This video shows the proper way to lubricate an AR-15 bolt-carrier assembly. The video identifies the key metal-on-metal friction points where you actually need lubrication: the rails on the underside of the carrier, shiny wear points on top, and just a dab on the cam pin. How much oil/lubricant should you use? The AR-15 is pretty forgiving on that point. Some spots work best with grease, others work best with a lighter oil. Just keep it out of the combustion areas. Those little holes in the carrier are gas vent holes, NOT oil holes!

AR Barrel Twist Rates — What You Need to Know

AR barrels can be ordered with a variety of twist rates from 1:12″ to 1:7″. Basically, the longer/heavier the bullet you plan to shoot, the faster the twist rate you need. For example, Sierra recommends a 1:7″ twist rate for the 90gr SMK. A 1:12″ could work with the small lightweight bullets up to 55 grains. The 1:9″ barrel will stabilize the light and mid-weight bullets up to about 77 grains. We recommend a 1:8″ or 1:7″ twist rate for the best versatility. You’ll find a detailed discussion of AR twist rates on

Barrel Gas Block Alignment — Key to Reliable Cycling

In this Tech Tip, Brownells gun tech Steve Ostrem explains surefire methods to align your gas block. The most common problem with AR builds is poor cycling, commonly caused by misalignment between the gas block and the barrel’s gas port.

Setting Up Gas Tube Systems

This Tech Tip examines AR-platform gas systems, and shows how to select the proper length gas tube, and how to configure multiple tube systems if you change your barrel to different lengths. This is worth watching for anyone re-barreling an AR.

How to Clean Your AR-15 — Helpful Maintenance Tips & Videos

AR15 AR AR-15 MSR black rifle cleaning maintenance bolt lubrication
Scottsdale Gun Club offers an AR-15 Cleaning Clinic on August 25, 2022.

AR-platform rifles can be maintenance-intensive beasts. They need regular inspection, cleaning, and lubrication. But some AR owners make the situation worse by not regularly cleaning important small parts, or by using too MUCH oily/greasy lubricants in the wrong places. A properly maintained and lubricated AR15 can shoot hundreds of rounds (between cleanings) without a problem. If you learn where (and where not) to apply lubricant, you’ll find that your AR will run more reliably and the task of cleaning the bolt, bolt carrier, and upper receiver internals will be less of a burden.

Here we showcase videos that show how to field-strip an AR-15, inspect the key parts, clean components, and lubricate internal parts as needed. Along with these videos, we recommend you read the comprehensive AR-15 Gun Cleaning Clinic article on the Brownells website. This explains in detail important procedures that the videos might only cover in a few seconds.

If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here are five videos that explain how to properly disassemble and clean AR-platform rifles.

AR15 AR-15 AR bolt carrier cleaning videos

1. How To Clean Your AR-15 | Cleaning and Maintenance Tips

This is a quick 90-second starter video that may help new AR owners. Ricky Lehnhardt of OTIS Technology demonstrates the basics of cleaning and maintaining your AR-15. Lehnhardt does a good job identifying the points that need cleaning on the inside of ARs. However he works very quickly in the video. You may want to pause the video at some points. Also, Lehnhardt employs a cable for pulling patches and brushes through the barrel. Yes this is fast and easy. However, for match AR rifles, we recommend that you instead use a cleaning ROD with fitted bore guide.

2. Take-Down and Full Cleaning of AR-15 by Jerry Miculek

Here ace shooter Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.

3. AR-15 Maintenance: Field-strip, Clean and Lubricate an AR-15

Gunsite Academy instructor and gunsmith Cory Trapp demonstrates the proper way to field-strip, clean, and lubricate an AR-15 carbine. In this 30-minute video, Trapp offers several important technical tips and hints. For example, at 11:05 Trap demonstrates how to determine if your bolt needs new gas rings. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.

4. AR-15 Dissassembly and Cleaning Guide

This video does a good job, with close-ups, showing how to remove the bolt carrier and clean the inside of the upper receiver. Then you can see how to work with various tools to clean the bolt, bolt carrier, and inside of chamber. We also recommend that you inspect the ejector recess and extractor recess. When we’ve inspected ARs that failed to cycle properly, we have often found nasty gunk (mixture of carbon, greasy lube, and brass particles) in these areas.

5. Basic AR-15 Quick and Easy Field Maintenance

In this NSSF-sponsored video, pro shooter Ryan Muller demonstrates basic, quick field maintenance of his AR-15. This would be for a quick cleaning and lubrication of the reciprocating parts. This covers rapid maintenance in the field. For full field-stripping and thorough cleaning, watch the previous videos.

Handy Mat for Cleaning AR Rifles

When working on an AR-15, it’s smart to have a pad that can absorb solvents and cushion your upper and lower. The $24.99 Real Avid Smart Mat is a good choice. This features printed take-down instructions and it has a handy parts tray on the right side. The mat rolls up for convenient storage. Click HERE to learn more.

Saturday Movies: Best Brownells Videos — Tools, Tips, and More

Brownells video archive youtube channel scope mounting air travel AR15 reloading .22 LR cleaning

Brownells is a well-known retailer of guns, gun parts, tools, accessories, ammo, and pretty much everything gun-related. What you may not know is that Brownells has a very active video production department that releases new “how-to” and product information videos every week. These videos offer helpful advice on gun cleaning/maintenance, reloading, as well as selecting/assembling components for various kinds of rifles. And every week Brownells serves up a new products video. There now over 1000 videos on the Brownells YouTube Channel, which is truly a remarkable resource.

Here are six of our favorite videos from Brownells. There’s a helpful guide to scope installation, AR owners will find some good advice on spare parts, new reloaders can learn how to use the OAL tool, and all gun owners should watch the video on ammunition storage.

Scope-Mounting — Common Mistakes to Avoid

Always be careful when mounting a rifle scope. This isn’t a super-complex or highly technical task, but there are ways you can mess it up. This video explains common pitfalls to avoid when mounting a scope.

1. Make sure the rings don’t touch ANY part of the turret housing, objective bell, or eyepiece.

2. Be certain the scope rings are tightly clamped to the scope base. Grasp the scope with one hand and the rifle with the other, then ensure there is no play.

3. Make sure there’s clearance between the objective bell and the rifle. No part of the scope should touch the rifle itself.

4. NEVER over-tighten the scope rings. You can actually crush the scope tube and damage the optic beyond repair. Stick to the torque specs!

How to Use Hornady OAL Tool and Hornady Bullet Comparator

Gun Tech Steve Ostrem explains how to properly use Hornady’s Overall Length Gauge to determine length-to-land precisely. The OAL Gauge uses a “Modified Case” that threads onto the tool and holds a bullet. Push on the back of the gauge until you feel the bullet just touch the rifling. (We do this gently at first, tapping the rod a couple time to ensure the bullet is aligned correctly). Once you’ve got the length, then use the tool with a comparator on your calipers to get the length-to-lands. NOTE: We recommend taking the measurement 3-4 times in a row to get a reliable number. With a little practice your should be able to get repeatable measurements within .0015″.

Air Travel with Firearms — Key Regulations You Must Follow

You can travel on commercial airlines with firearms. But you must follow the TSA regulations, and your particular airline’s rules. First, make sure your guns are UNLOADED before your leave home. Guns need to be carried in proper hard-sided cases that cannot be pried open. Be prepared to unlock the case if the TSA wants to inspect what’s inside. TSA agents can cut the locks if they need to open the case but can’t locate you. If you use special TSA-approved locks, TSA agents have master keys that let them open the case without destroying your locks. You CAN transport up to 11 pounds of ammunition — with restrictions explained in the video.

How to Store Ammunition Safely and Securely

This has been one of the most popular Brownells videos — with over 1.7 million views. Here’s the deal — ammunition WILL keep for a long time if you store it properly. DO store ammunition in a cool, dry place that doesn’t have wide temperature swings. Temperature cycling will also degrade primers and powder. Put it in airtight ammo cans to keep out the moisture. Tupperware containers will work too. Brownells also recommends putting moisture-absorbing silica packs in your ammo containers. DON’T just keep ammo in factory cardboard factory boxes stacked in the basement, attic, or garage (especially on the floor). Factory ammo boxes can absorb moisture which can degrade primers and corrode the brass cases. Yes, sealed military ammo will usually handle this kind of storage for quite a while, but it’s still not wise.

Must-Have Spare Parts for AR-Platform Rifles

In this video, two knowledgeable gun techs answer the question: “What spare parts should I keep on hand for my AR-15?” On the list are: Gas Rings, Buffer Spring, Extractor Spring and Pin. NOTE: You may want to try the one-piece spiral gas ring rather than the standard rings which require alignment. The cotter pin and cam pin can also easily get lost when the Bolt Carrier Group is disassembled for cleaning. On the lower receiver you’ll want spare springs and detents for the pivot/takedown pins. If you’re using lighter-power springs, keep standard-power spares on hand. If your rifle stops working, swap in the factory-spec springs to find out if the problem is the gun or your ammo. Also, if you have upgraded your trigger, always keep the original trigger as a backup.

Cleaning Advice for .22 LR Rimfire Rifles

Gun Techs Steve Ostrem and Caleb Savant debunk some myths about cleaning .22 LR barrels. One myth is that cleaning will harm the accuracy of a .22 LR barrel. Caleb thinks this myth is the result of people cleaning a barrel from the muzzle and damaging the muzzle crown, which CAN diminish accuracy. If it’s done right, cleaning won’t damage the bore. However, you certainly do NOT have to clean your 22 LR’s bore every time you go to the range. But DO clean the action every time you shoot the rifle, especially on a semi-auto. What about shooting a lot of lead bullets? Won’t that lead up the bore? The guys give us the straight skinny on lead fouling, too. When you see your .22 LR rifle’s groups opening up, you may want to consider cleaning.

Ultrasonic Case Cleaning — Determining the Optimal Dwell Time

cartridge brass case ultrasonic liquid cleaning dwell time brownells

If you read our lengthy article on Ultrasonic Case Cleaning by Jason Baney, you’ve seen the remarkable results that can be achieved with this method, as shown by the photo above. Ultrasonic cleaning has many advantages over traditional tumbling methods of case cleaning. There is no dust or media residue to remove from the brass, and when done right, the cases come out clean and shiny, inside and out, even the primer pockets.

In its Benchtalk Archives, Brownell’s has an excellent article discussing Ultrasonic Case Cleaning. Brownell’s staff compares results, with measured dwell times from 5 to 75 minutes, using both Mpro-7 and HCS 200 cleaning solutions. Tests are performed with once-fired and 5X-fired Tactical 20 (Tac20) cases, as well as once-fired .260 Rem Cases. The article also compares the results from ultrasonic cleaning vs. tumbling in walnut media. Below are Brownell’s results for Tac20 cases with the HCS 200 (non-acidic solution). Go to Brownell’s article for MPro7 results and Rem 260 results.

HCS 200 Cleaning Solution Test

Procedure — Solution was de-gassed for 15 minutes, then 63 Tac20 cases were placed in a single layer, in stainless steel mesh basket. The temperature of the starting solution was 102° F. When the cases were removed the temperature was 110° F.

Once-Fired Tactical Twenty Cases (HCS 200) — Observations
5 minutes: The exterior of the cases are not significantly brighter/cleaner. The primer pockets and case interiors are still dirty.
10 minutes: Exterior of the cases are brighter. 70% of the cases show some degree of cleaning of the primer pockets. Little difference seen inside the case, but case mouths are cleaner.
15 minutes: Case brightness is about the same. Still only 70% of the primer pockets are clean, but a larger portion of each is cleaner. A Q-tip swabbed inside the cases shows that carbon/powder residues are loosening up.
20 minutes: Case exteriors are brightening up. 80-85% of the primer pockets are about 90% clean. The insides of the cases and case mouths are cleaner.
25 minutes: Cases are brighter/cleaner than even new brass. 80-85% of the cases have almost completely clean primer pockets. The inside of the cases are 80-90% clean.
30 minutes: The insides of the cases and case mouths appear to be completely clean. 87% of the primer pockets are virtually 100% clean. 13% of the cases had stubborn primer pocket residue that could not be completely removed.
60 minutes: Eight cases (13%) were placed in the tank for another 30 minutes to try to remove the remaining residue in their primer pockets. Six out of the eight cases were completely clean.

Five-Times Fired Tac20 Cases — Observations
30 minutes: Based on the above observations, I didn’t begin to observe these 5-time fired cases until after 30 minutes: The exterior cases are bright/clean. Brighter than new cases. The primer pockets on 75% of the cases are 75% clean. The remaining cases had primer pockets that were only 25% clean. The inside of the cases appear to be clean.
65 minutes: 25% of the primer pockets were 95% clean, 25% of the primer pockets were 90% clean, 25% of the primer pockets were 85% clean; and 25% were 80% clean.
75 minutes: 75% of the primer pockets were 90% clean.

How Does Ultrasonic Cleaning Work?
The Brownell’s Benchtalk article explains: “Ultrasonic cleaning uses high-frequency sound waves (generally between 20-80 kHz) to remove a variety of contaminants from objects immersed in a liquid. The result of these high-frequency sound waves is a process called cavitation. These high frequency bursts of ultrasonic energy produce a three-dimensional wave of alternating positive and negative pressure areas as the sound wave passes through the solution. During negative pressure, microscopic cavitation bubbles form and will continue to grown until they reach resonant size. As the positive sound wave passes, the pressure rises rapidly and implodes these tiny bubbles. Before these minuscule bubbles implode they store a tremendous amount of energy. These bubbles can be as hot as 10,000 degrees and have as much as 50,000 lbs per square inch of pressure. This sounds alarming, but you have to remember that these bubbles are microscopic in nature and pose no harm to anything, unless you are a carbon /powder residue deposit on a cartridge case!

When this cavitation bubble implodes near your brass case, it transforms the bubble into a jet about 1/10th of its size. This jet of energy can travel as fast as 400 km/hour. At 43 kHz, as is the frequency for our L & R HCS 200 ultrasonic cleaner, this is happening 43,000 times per second. This micro-burst of extreme energy is responsible for removing contaminants from the surface of your cartridge brass. Ultrasonic cleaning can reach into crevices and inaccessible areas and remove surface debris that can’t be cleaned by any other process.”

Whether shooting at matches or just target shooting having a good spotting scope is a must. A great choice is this Kowa TSN-82SV Combo on sale for $975, a $110 savings. This item includes the highly-rated 82SV spotting body, plus an excellent 25X LER (Long Eye Relief) eyepiece AND a deluxe protective cover. NOTE: With its fixed-power Long Eye Relief eyepiece, this scope works great for prone work, mounted right next to the shooter.

These are handy “reactive” targets that show a yellow splatter on shot locations. Each roll contain 250 three-inch-square stick-on grids. Each sticker has nine 1″ squares on it so determining group size is easy. For a shooter with an accurate rifle, these 3″ x 3″ splatter squares can work better than a large splatter bullseye target.

There is a zipper-access top compartment and a large secondary compartment (with inner mesh pocket and MOLLE straps) to hold ammo, Kestrel, muffs, targets, or other accessories. We like this case to carry a carbine with folding stock. It’s a steal at just $49.99.

Weaver Rail vs. Picatinny Rail — What’s the Difference?

Picatinny Rail specifications 1913 Mil-std

Readers often ask “What’s the difference between a Weaver scope rail and a Picatinny Rail?” The answer is not as simple as it seems. The dimensions of a Picatinny Rail should be consistent (from one rail-maker to another), since there IS a government spec. Conversely, there is some variance in “Weaver-style” rails. The width of the groove is the most important difference between Picatinny Rails and Weaver-type rails. “Mil-spec” Picatinny rails will have a grove width of 0.206″ while Weaver rails typically have a narrower, 0.180″ groove width.

Weaver Rail BAT action
Does your rifle have a Weaver Rail or Picatinny Rail? Check the dimensions to be sure.

Brownell’s has a helpful GunTech™ Article that discusses the Picatinny Rail vs. Weaver Rail. That article explains:

What are the differences between the ‘Picatinny’ and the ‘Weaver’ systems? The profile of the two systems is virtually identical. Depending on the quality of the machining done by the manufacturer, the two systems should be indistinguishable from the profile. The key difference lies in the placement of the recoil grooves and with width of the grooves. MIL-STD-1913 (Picatinny) grooves are .206″ wide and have a center-to-center width of .394”. The placement of these grooves has to be consistent in order for it to be a true Picatinny MIL-STD system. Weaver systems have a .180” width of recoil groove and are not necessarily consistent in a center-to-center measurement from one groove to the next.

picatinny weaver rail specifications diagram brownells 1913 Mil-std

In many instances, a Weaver system has a specific application that it is machined for, so interchangeability is not necessarily an issue. A MIL-STD-1913 system must adhere to the specifications listed above in order for it to be considered MIL-STD, since the military desires uniformity in the recoil grooves to allow for different systems to be mounted on the weapon with no concern for compatibility.

Now, what does this mean? Boiled down, it means that accessories designed for a Weaver system will, in most cases, fit on a Picatinny system. The reverse, however, is probably not the case. Due to the larger recoil groove, Picatinny accessories will not fit a Weaver system. There are, of course, exceptions to every rule, but for a good rule-of-thumb, [full-width] Picatinny won’t fit Weaver, but Weaver accessories WILL fit Picatinny.

Brownells Gives $60K to Fight Washington State Magazine Ban

brownells SAF second amendment foundation washington state magazine ban lawsuit challenge

Brownells donated a check for $59,884 to the Washington-state-based Second Amendment Foundation (SAF) to help fund the lawsuit against the state’s ban on standard-capacity magazines signed into law on March 23, 2022.

“The Second Amendment Foundation really appreciates the financial support that Brownells has given us to make our lawsuit possible,” said Alan Gottlieb SAF Executive Vice President. “This is not the first time Brownells has helped fund our [Second Amendment Rights Litigation efforts].”

brownells SAF second amendment foundation washington state magazine ban lawsuit challengeBrownells raised the funds during its “Mag Dump for Washington State” event – lasting from March 14 until June 24, 2022. The event promised consumers that a percentage of sales from every Brownells aluminum 30-round magazine sold would be donated to aid in SAF’s Washington legal effort.

“Brownells is a passionate defender of the Second Amendment”, said Ryan Repp, Brownells VP for Marketing. “We support several pro-Second Amendment organizations, but we see SAF as a stalwart in the fight preserve our Constitutional freedoms. It’s a pleasure to make this donation to aid in their fight to help the citizens of Washington”.

Washington state residents took advantage of the Mag Dump to purchase reliable standard-capacity magazines during the grace period between the day Senate Bill 5078 was signed into law and July 1, the day the magazine ban took effect.
