NEW Rifle Load Development and Scope Testing Target

Box to Bench Precision Scope tracking load development target

An outfit in Washigton State, Box to Bench Precision, has developed an oversize (23.5″ x 30″) precisely-scaled target designed for load development and scope testing. This target is very innovative. On the target you’ll find various clusters of aim points for various tasks. Upper left are orange aiming spots for testing various powder charges. In the upper right quadrant are more red aim points to be used when testing bullet seating depth. Running down the center of the target is a vertical line with horizontal marks showing precise MOA and Mil heights at 100 yards — use this feature to verify your click values.

This waterproof 23.5″ x 30″ target costs $6.99 from BoxtoBenchPrecision.com:

And there’s more. In the lower right quadrant (far right) are three black targets to be used for chrono work. With these you can record cold velocity, hot barrel velocity and a “Final Velocity”. Over in the lower left quadrant, in the left-most column, are three dot targets for zeroing and recording group size with load data. Finally, four more black/white targets can be used for a scope box test (aka “shooting the square”). With a box test, you move from target to target, clicking in sequence to each corner of the square in sequence, evenutally returning to your original aim point. If your scope tracks correctly, the last box test shot should end up right on top of the first shot.

Record the Entire Load Development Process on One Target
For those used to shooting at conventional bulleyes or benchrest targets, this target may seem confusing, but it can really help organize and simplify the process of load development. We like the idea of having a single, durable target that performs double-duty — serving for load development as well as scope checking. And we like the fact that the target is pretty strong — the maker says: “The target is Tear-Resistant and Water-Proof”. We’d expect a maker based in the Pacific NW to design a target that can handle wet weather.

How to Order
So how much does all this target technology cost? A single, 23.5″ x 30″ target costs $6.99. A pack of three targets costs $19.47, while a five-target pack runs $29.95 (which works out to $5.99 per target). Targets ship in a durable cardboard tube.

Precision Reloading for Handguns — Smart Tips from the USAMU

USAMU Service Pistol Handgun Tip Advice Reloading

The U.S. Army Marksmanship Unit (USAMU) fields pistol teams as well as rifle and shotgun competition squads. Consequently the USAMU’s Reloading Shop loads tens of thousands of pistol rounds every year. In this article, the USAMU’s handgun experts talk about reloading for handguns — with smart tips on how to achieve superior accuracy with 100% reliability. If you load for pistols, take the time to read this article, which offers important insights on COAL, primers, crimps and more.

USAMU Service Pistol Handgun Tip Advice Reloading

Optimize the Taper Crimp
One often-overlooked aspect of handloading highly-accurate pistol ammunition is the amount of crimp and its effect on accuracy. Different amounts of taper crimp are used with various handloads to obtain best accuracy. The amount is based on bullet weight, powder burn rate and charge, plus other factors. It is not unusual for our Shop to vary a load’s crimp in degrees of 0.001″ and re-test for finest accuracy.

USAMU Service Pistol Handgun Tip Advice ReloadingUse Consistent Brass
Brass is also important to pistol accuracy. While accurate ammunition can be loaded using brass of mixed parentage, that is not conducive to finest results, particularly at 50 yards. It is important for the serious competitor/handloader to use brass of the same headstamp and ideally one lot number, to maximize uniformity. Given the volumes of ammunition consumed by active pistol competitors, using inexpensive, mixed surplus brass for practice, particularly at the “short line” (25 yards), is understandable. However, for the “long line” (50 yards), purchasing and segregating a lot of high-quality brass to be used strictly for slow-fire is a wise idea.

Importance of Uniform COAL
Uniformity of the Case Overall Length (COAL) as it comes from the factory is also important to achieving utmost accuracy. More uniform case lengths (best measured after sizing) contribute to greater consistency of crimp, neck tension, ignition/burn of powder charge, and so on. Cartridge case-length consistency varies from lot to lot, as well as by maker. Some manufacturers are more consistent in this dimension than others. [Editor’s note: It is easy to trim pistol brass to uniform length. Doing this will make your taper crimps much more consistent.]

Primers and Powders — Comparison Test for Accuracy
Pay attention to primer brands, powder types and charges. Evaluating accuracy with a Ransom or other machine rest at 50 yards can quickly reveal the effect of changes made to handload recipes.

Bullet Selection — FMJ vs. JHP
Bullets are another vital issue. First, there is the question of FMJ vs. JHP. A friend of this writer spent decades making and accuracy-testing rifle and pistol bullets during QC for a major bullet manufacturer. In his experience, making highly-accurate FMJ bullets is much more difficult than making highly-accurate JHPs, in large part due to the way the jackets are formed. Small die changes could affect accuracy of FMJ lots dramatically.

The CMP now allows “safe, jacketed ammunition” in Excellence-in-Competition (EIC) Service Pistol matches, although wadcutter ammunition is prohibited. Thus, the option to use very accurate JHP designs simplifies the life of CMP Service Pistol shooters in pursuit of the prestigious Distinguished Pistol Shot badge.

Hopefully, these tips will be helpful to any pistol shooters interested in accurate handloads, not just “Bullseye” shooters. Small tweaks to one’s normal routine can pay big dividends in improved accuracy and make practice and competition more rewarding.

Stay safe, and good shooting!
