Saturday at the Movies: Five Great Videos for Accurate Shooters

AccurateShooter Daily Bulletin Saturday Movies Videos Barrel cleaning neck turning autotrickler reloading components

Every Saturday we present interesting, informative videos for our Daily Bulletin readers. Here we feature five YouTube videos that offer a ton of useful information for serious shooters. We start with a great video about setting up rifle, rest, and bag on the bench. Then Hall-of-Fame benchrest shooter Speedy Gonzalez shows smart methods for cleaning barrels. Next F-Class Ace Keith Glasscock explains how to optimize your rifle after travel. In the fourth video, AutoTrickler inventor Adam MacDonald shows how to optimize the AutoTrickler V4. Next the truly outstanding 21st Century Power Neck-Turning lathe is showcased.

How to Set Up Your Rifle, Rest, and Bag on the Bench

To get the best results in benchrest shooting, you need to set up all the gear on your bench properly. That includes front rest placement, rear bag position, spotting scope set-up, and placement of cartridge holder/caddy, and possibly an elbow/forearm rest. When setting up the hardware, you need to align the front rest and rear bag properly to get optimal tracking. In addition you want to make sure the rear bag doesn’t slide or rotate a bit from shot to shot. And you also want to set your seat height/location so the shooter’s position is optimal and comfortable. This helpful video shows how to set up your rifle and gear for a benchrest match or load development/practice at the range. Credit to Boyd Allen for finding video.

Cleaning Barrels with Speedy — Smart Techniques

There are many effective methods to clean barrels. But some are more efficient that others and can help you do the job more quickly, with less effort. Here respected gunsmith and Hall-of-Fame benchrest shooter Speedy Gonzalez shows his procedures for cleaning competition barrels. He uses Sharpshoot-R Liquid Patch-Out and Wipe-Out Accelerator as primary solvents. Watch carefully — Speedy has some clever techniques for starting a patch in the rifling, and he is also careful about exiting the muzzle when brushing. Speedy also explains the importance of keeping your rods clean. And he prefers nylon brushes because, as the barrel starts to get wear in the throat, “the bronze bristles will actually start eating into that and you’ll see little grooves if you have a good borescope.” (See video 00:38-01:35)

Getting Rifle Ready After Traveling — Keith Glasscock

Keith Glasscock is one of America’s top F-Class shooters, having finished Second at the National Championships multiple times. Keith, who has an engineering background, runs the popular Winning in the Wind YouTube channel. There you’ll find great advice on wind reading, load tuning, precision reloading and many other topics. In this video, Keith offers very smart advice on how to re-assemble your rifle after you have traveled to a match or practice destination. Keith explains how to check the fasteners on the gun and set up the scope properly if you removed it while traveling.

Adjusting AutoTrickler V4 with its Inventor, Adam MacDonald

Adam MacDonald is the brilliant Canadian engineer who created the AutoTrickler series of automated powder dispensing systems. These work with advanced scales to dispense powder rapidly, but with a precise final trickle accurate to a single kernel. In this video, Adam explains how best to adjust and calibrate the AutoTrickler V4 when using powders that flow at different rates.

21st Century Power Neck-Turning Lathe — Great Tool

Turning case-necks can be tedious and tough on older hands if you’re using hand-held tools. Quite a few years ago 21st Century released a great compact, neck-turning lathe that delivers superb, consistent results. This Editor uses that original lathe with hand crank and I can affirm that it works great. It is easy to use, fast, and the turned necks come out smooth with consistent rim thickness. But you still had to turn a crank. Well, in 2018, 21st Century created an upgraded Power Neck-Turning Lathe with an electric motor and lever to advance the cases to the cutter. The power head glides on stainless steel guide rails. Power is controlled with a red button in the feed handle.

This advanced, powered mini-lathe is absolutely superb. It works brilliantly and makes the task of turning case-necks fast and VERY easy. And there is even a 3-Way trimmer upgrade that will trim cases to length at the same time as the necks are turned.

BONUS — How to Spot Fake Online Sellers of Components

With the shortage of premium reloading components, particularly powder and primers, many handloaders are desperate to find components when even big companies such as Midsouth and MidwayUSA are completely sold out. Enter the scammers. There are criminals, many based overseas, who have created entire websites designed to steal your money. You might find such a site when searching for “Varget powder in stock” or “CCI BR4 primers”. These sites look like regular business webstores, with product photos and modern shopping cart systems. But it’s all a scam.

Key giveaways are: 1) The site does NOT take Visa, Mastercard, or Discover but requires payment with Zelle, Venmo, Bitcoin, or AppleCash only; and 2) The site has hard-to-find powders, such as Varget and H4350, that nobody else has, and you can put thousands of pounds in the shopping cart.

Bottom line here — if the site allows you to order vast amounts of powder and/or primers, and does not take ANY major Credit Card types, it is almost surely a scam. If you see links to pay with Crypto-Currency (such as Bitcoin) run away!

Bryan Litz Explains CWF — Crosswind Weighting Factor

Bryan Litz Applied Ballistics CWF Crosswind Weighting Factor

Bryan Litz, founder of Applied Ballistics LLC, has a new Facebook page where, multiple times every week, he posts useful ballistics info and shooting tips. We recommend that Facebook users check out the new Bryan Litz Ballistics Facebook page. Here is one interesting example from that page. Bryan analyzes the Crosswind Weighting Factor (CWF). The Crosswind Weighting Factor (CWF) shows where a bullet’s trajectory is most susceptible to wind. By understanding CWF, shooters can better predict how wind affects bullet flight, especially at extreme ranges, when the projectile has gone transonic.

Crosswind Weighting Factor (CWF) graphs show where bullet trajectories are most susceptible to wind.

Where does the wind have the most effect?
At the shooter?
At the target?
Halfway?

Bryan Litz explains: “Out through the supersonic range, the CWF is maximum at the shooter. However as the trajectory extends into transonic, the max CWF gets pushed down range. That’s because the greatest segments of lag time in the bullets trajectory are at transonic where the drag coefficient is maximized around Mach 1.” [Editor: So if your bullet stays fully supersonic during its flight to your target, you can normally expect the CWF to be highest at your shooting station. But once the projectile drops into transonic speeds then the situation changes.]
