North America’s top female action shooters converged on St. George, Utah recently for the Brownells Lady 3-Gun Pro-Am Challenge West Match. Dozens of competitors from the USA and Canada attended this event which featured some amazing stages. Check out the video of the Roller Coaster Stage — bet you never saw anything like THAT at a shooting match before. (This Roller Coaster side-match raised funds for Urijah Smith, a two-year-old boy suffering from cancer.)

Team Smith & Wesson shooter Julie Golob has a message for Mother’s Day (Sunday, May 10th). Julie writes: “While some are using Mother’s Day week to push a gun control agenda, I’d like to encourage moms to ‘Take a Moment’. Talk to your kids about firearms safety. Help them learn what to do around firearms and have an open, honest discussion about guns and gun safety.
I truly believe that, no matter if you are pro-gun or anti-gun, everyone should know and understand the basic rules of firearm safety. It is equally important for parents to have the discussion about guns and what to do if your child finds one. Both the NSSF’s Project ChildSafe and the NRA’s Eddie Eagle GunSafe® Program are excellent. They offer resources for parents, educators, and child care providers to help ensure kids stay safe.
In this video, Julie encourages parents to have “the talk” about firearm safety with their kids sooner rather than later, and provides tips for how to have a helpful discussion. Sherra Scott, a mom and a certified NRA instructor, agrees with Julie: “Whether you have firearms in your home or not, if you have children in your life, please watch this video and talk WITH them about firearm safety and what to do if they come into contact with a firearm.”
The Lee Breech-Lock Hand Press is a useful addition to a serious reloader’s tool collection. This handpress allows you to resize brass or seat bullets while at the range or away from your loading room. No it won’t replace your Co-Ax or Rockchucker, but this is a handy press to have. And right now it’s very affordable. Currently, Midsouth Shooters’ Supply is selling the Lee Breech-Lock Hand Press Kit for just $52.86. That’s a great deal.
This Kit comes complete with: Breech Lock Hand Press, Ram Primer fittings, Powder Funnel, Case Lube, and one Breech Lock Quick Change Bushing. Note: the maximum overall length cartridge the Lee Hand Press can accept is 3.650 inches.
Following Sierra’s introduction of Tipped MatchKing (TMK) bullets, Bryan Litz of Applied Ballistics LLC has received many requests to determine the Ballistic Coefficient (BC) of these bullets through testing. Below are Litz’s findings for four out of the six bullets he has able to acquire and test so far.
As you can see from the above table, when Sierra’s G1 BC is averaged for all speed ranges (which is representative of long range shooting) the results closely match the Applied Ballistics’ measurements of the same bullets, averaged from 3000 to 1500 FPS. The G7 BC doesn’t suffer nearly the velocity sensitivity as G1 and should be used for modern long range bullets when possible. Bryan tells us: “When I get the .22 caliber 77gr, and the .308 caliber 168gr tested, I’ll update the table.”
How do these Tipped MatchKings compare to standard MatchKings? According to Bryan’s measurements, here are some comparisons:
The 69gr TMK BC is +8% compared to the 69gr SMK
The 125gr TMK BC is -5% compared to the 125gr SMK (Litz believes this SMK was ‘pointed’)
The 155gr TMK BC is identical to that of the 155gr SMK (#2156, which is also pointed)
The 175gr TMK BC is +10% compared to the 175gr SMK
Bryan provided this additional advice for users of Ballistics programs: “Sierra’s stated BCs are measured by live fire, and are typically pretty accurate if the velocity bands are properly observed (7mm being the exception). A common error is to look at the BC that Sierra gives for your MV and just use that. Doing so overestimates the performance of the bullets over long range, and will cause you to hit low compared to your trajectory predictions.”
Jason Baney was one of the “founding fathers” of this website when we started out as 6mmBR.com a decade ago. Jason’s latest project involves an interesting wildcat, a mid-sized 7mm cartridge based on the 6.5×47 Lapua case. In this report, Jason (who now works at Eurooptic.com) talks about the 7×47 wildcat and his initial velocity (and feasibility) tests. To determine the 7×47’s velocity potential, Jason did a multi-stage test, cutting a barrel in two-inch increments. This process is illustrated in a video, embedded below. You may be surprised that the little 7×47 cartridge could drive a 180gr Berger Hybrid at 2770+ FPS with a 32″ barrel and Reloder 17. Max Velocity with H4350 (and 32″ barrel) was roughly 70 FPS slower. With a 24″ barrel length, the 7×47 was still able to propel the 180gr Hybrids over 2600 FPS with H4350. That’s impressive performance for a mid-sized cartridge pushing a very big bullet.
7×47 Lapua Part 1: Velocity Study

The biggest enemy in long-range shooting is wind. This also happens to be the hardest to gauge and predict. The only way mere mortals can attempt to defeat the wind demons is to shoot a cartridge with the most ballistic efficiency, yet maintain a user-friendly combination of recoil and component consumption as well as performance on target.
The 7mm bullets tend to yield the best compromise of all of these aspects. Their BC-to-weight ratio is outstanding and 7mm bullets provide sufficient impact energy for most situations. In addition to that, the recoil of 7mm bullets can be more manageable than heavier/larger .30 and .338 caliber projectiles.
In cartridge design, of course you want the best case possible. Having used the 6.5×47 Lapua since its release in 2006, I felt this cartridge was the perfect choice to start with as I wanted a true short-action non-magnum round that gave the least possible wind drift to 1000 yards. The 6.5×47 parent case also allowed seating of the heavy 180gr class bullets completely out in the neck yet it maintained an overall length that would actually work in a factory Remington short action magazine.
Here’s great news for fans of wildcat cartridges and for any hand-loaders who need dies with custom dimensions. Redding Reloading Equipment will now be making custom dies again. The procedure for ordering dies is outlined below. You’ll need to provide a chamber reamer print or three fired cases.
Redding is now able to offer custom dies because it has expanded its manufacturing capabilities in recent years. Redding has more than doubled the number of its CNC machines, expanded factory floor space by 40%, and added many new skilled workers. This growth in production capabilities has allowed the company to again accept orders for new Custom Dies and Die sets.

This article, in longer form, appears on the USAMU Facebook page, as part of the “Handloading Hump Day Series”. This article explores three different “Philosophies” of precision reloading. Some handloaders seek to produce ammo that yields the very tightest groups (without factoring in the wind). Other shooters load their ammo to deliver the highest safe velocity. That’s because a projectile launched at higher velocity will drift less in the wind. The theory is that even if fast ammo doesn’t produce the tightest groups in zero wind conditions, it will yield higher scores in a the real world (where the wind blows). Lastly, some handloaders favor ammo that is ultra-consistent across a wide temperature range. This last philosophy dictates selection of a powder that is temp-insensitive, even if it may not produce the very best raw accuracy (or speed).
What’s Your Handloading Philosophy?
Objectives of Reloading — Accuracy, Velocity, Temp Stability What do you, the reader, primarily value in your handloads?
Viewpoint ONE: Accuracy Trumps Everything
Some shooters prize consistent, excellent medium/long range accuracy enough that they’re willing to give up some extra velocity (and reduced wind deflection) to obtain that. Their underlying philosophy could be stated: “Superior accuracy is present for every shot, but the wind isn’t”. One’s ability to hold well, aim well and read the wind are all factors in making this type decision. The photo below shows stellar raw accuracy. This is an 0.67″, 10-shot group at 300-yards fired from a text fixture. The group measures just 0.67″. (This shows the USAMU’s 600-yard load with 75gr bullets).
Anette Wachter (aka ’30CalGal’) is one of America’s top long-range sling shooters. A member of the U.S. National Rifle Team and a NRA High Master (both mid- and long-range), Anette has an impressive shooting resume. She has also recently started shooting 3-Gun and tactical matches. These “run and gun” matches involve rapid transitions, with shooting from a wide variety of positions. To help improve her 3-Gun shooting, Anette has developed a specific exercise regimen, which she calls the 3-Gun Biceps Series. Here’s a short sample:
ANETTE: One thing you can be sure of in a 3-Gun match is shooting from weird positions. I have noticed that the stage designers love port holes [in barriers]. There are many that are on the ground that you have to shoot through. Or perhaps it is not a port hole but just underneath a barrier. Imagine you are running to that spot with rifle in hand and you have to use one arm to brace your fall to the ground, while holding the rifle safely and facing down range in the other, and then get in to position to shoot, then back up again using one arm to push off of. I have an exercise I have been doing for a awhile that works great for this move…

If you are considering purchasing a new optic for your favorite rifle, you should read a recent article by Robert Abrams that appears on the Target Shooter Magazine Website. Abrams, a Canadian shooter who runs the Rifletalk.org Blog, considers a wide spectrum of optics, from bargain-priced models to top-of-the-line scopes from Nightforce and Schmidt & Bender. In comparing optics, Abrams considers a variety of factors including: Optical Clarity, Controls Function, Cost, Reliability/Durability, and Warranty.
Abrams leads off with this invaluable bit of advice: “I have owned a lot of scopes and the reason I’ve owned so many is because, like most people, I made the mistake of ‘false economy’ — initially buying cheap scopes. Today, I firmly believe the old adage ‘only a rich man can afford cheap glass’ and thought it was about time that I shared some of my observations about a few of the optics choices out there.” To prove his point (that buying cheap glass is ‘false economy’) Abrams reviews the full spectrum of optics, from low-end to high-end:
