Brass

This post is about the bullets, powder, and brass the best precision rifle shooters are using. It is based on what the top 50 long-range shooters nationwide brought with them to the Precision Rifle Series (PRS) Finale a couple weeks ago. Target engagements for a PRS match can range from 25 to 1,200+ yards, but there is definitely a focus on the “precision” rifle part regardless of the range. For more info on who these guys are, and why you should care what they think scroll to the bottom of this article. Update: These are results from the 2013 PRS Season. The ...

Back in 1993, Precision Shooting Magazine printed a landmark article about the findings of a group of benchrest shooters who turned a huge Houston warehouse into a precision shooting laboratory. The warehouse, owned by Virgil King, included a 325 yard long straight-away through the heart of it, which provided an ideal shooting environment where the breezes never blew, the mirage never shimmered, the sun never set and the rain never fell. So began the most insightful, revealing experimentation into practical rifle accuracy ever conducted. Over a period of six years, the levels of accuracy achieved in the Houston Warehouse went ...

These are all of my pet loads. They were what I found to be the most precise in my rifles after extensive and tedious load development. I may tweak the loads slightly as the throat of a barrel erodes, but I don’t typically vary too far from what is shown here. In fact, this is the page that I personally reference when I need to remember the details of one of my loads. You should always reference a quality reloading manual and start with the minimum recommended loads, and work your way up. Just because these have proven safe in ...

I shoot a 7mm Remington Magnum, and when I started handloading for it I began by looking for a high quality brass case.  I started by looking to see if Lapua made cases for a 7mm Rem Mag, and although I didn’t see any for sale through MidwayUSA or Sinclair … I did find some mixed opinions on whether Lapua had ever made cases for belted cartridges, and the 7mm Rem Mag in particular. Then earlier this year while I was at Shot Show, I was at the Lapua booth and noticed in their new VihtaVuori Reloading Guide they actually ...

I recently weighed 100 pieces of brand new Lapua 223 Remington “Match” brass, and honestly I’m disappointed.  A few people have been telling me how good Lapua brass was, so I was simply expecting more consistency than what I found.  It didn’t stack up well compared to some Norma brass I weighed recently … although the overall quality appears to be good.  In fact, it wasn’t much different than weight distribution of some super-cheap, once-fired Remington 223 brass I bought for 1/5 of the price (the average deviation of the Lapua brass was actually higher).  Here is the resulting data for the Lapua brass, so you can compare for yourself: Average ...

I’ve been using Norma’s brass for the 7mm Remington Magnum lately, and thought I’d write a review over what I’ve found so far. Norma is a high-end, European brass manufacturer similar to Lapua.  They use the highest quality raw materials, and have very narrow tolerances and tight quality control.  Like Lapua, they drill the flashholes on their brass instead of punching them.  Almost all other brass manufacturers punch their flashholes, which can cause inconsistency and require that you debur the flash hole. Also like Lapua, Norma anneals the neck on all of their brass.  However, that isn’t as apparent as it is ...

Many handloaders believe an accurate load starts with quailty brass.  The more uniform the brass, the better accuracy you can expect.  So there are a lot of questions that commonly arise: What is the best brass? Should I use “once fired” or “military surplus” brass? Is quality of Lapua brass really worth the added cost? I stumbled upon some info on 6mmBR.com about a year ago containing some data that can be used to compare of brass uniformity between manufacturers.  I’ve tried to refer back to article several times … but I always have a hard time finding it again, because it is buried in ...

I recently weighed 153 pieces of once-fired Remington 223 brass that had all been full-length resized, trimmed to length, deburred, primer pockets uniformed, and neck turned.  Here is the resulting data: Average = 90.8 grains Standard Deviation = 0.71 grains Average Deviation = 0.53 grains (average of the absolute deviations of the data points from the mean … 0.53gr actually isn’t that bad) Variance = 0.51 Extreme Spread = 4.0 grains Extreme Spread as % of total weight = 4% (this is significant) All data was gathered using a RCBS ChargeMaster 1500 Powder Scale, which is accurate to +- 1/10 grain and was calibrated ...
