NF ELR Calibers & Cartridges – What The Pros Use

ELR Caliber Comparison

Over the past few weeks, I surveyed over 100 shooters who competed in this year’s Nightforce Extended Long Range Steel Challenge in Wyoming. I know a lot of you had questions about calibers, scopes and other gear guys were using, so I put together a survey, and the match director, Scott Satterlee, sent it to all the competitors. Over 100 shooters completed the survey, including 85% of the guys who finished in the top 25 overall. Thanks to all the guys who took the time to share. One of the fun things about the NF ELR match is it has ...

Nightforce ELR Steel Challenge

Wyoming ELR Match

A few weeks ago, I attended one of my all-time favorite matches: the Nightforce ELR Steel Challenge hosted by Scott Satterlee in Wyoming. It was quite the experience, with targets ranging from 720 to 2,091 yards and sustained winds over 30 mph! A few competitors measured gusts up to 50 or even 60 mph! Believe it or not, you can still hit targets in those conditions – and some shooters hit first round with surprising consistency. This Wyoming ELR match is the only match like it anywhere in the country. Because it is so unique, it isn't affiliated with the PRS, NRL, or other series, which means many shooters may not be aware of it and that is why I wanted to share an after-action report about it with my readers.

How Much Does Cartridge Matter?

As long-range shooters, we tend to obsess over every little detail. After all, we’re trying to hit relatively small targets that are so far you may not even be able to see with the naked eye. While you might can get away with minor mistakes and still ring steel at short and medium ranges, as you extend the range those small mistakes or tiny inconsistencies are magnified. So, most things are important … but to differing degrees. This series of posts is taking a data-driven approach by using Applied Ballistic’s Weapon Employment Zone (WEZ) analysis tool to gain insight into how different ...

Rifle Reloading Data: My Pet Loads for Target & Hunting

These are some 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. 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 my rifles, doesn’t mean they will be in your’s. Chamber dimensions, brass specs, barrel grooves and diameter can vary, so it’s very important ...

Lapua Brass for 7mm Rem Mag?

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 ...

7mm Rem Mag Load Development Part 4: 5 Shot Groups

I’ve already done quite a bit up to this point in my load development.  At this point I know I want to try to find an accurate load for Berger’s 168gr VLD over Hodgdon’s Retumbo powder and I’m now zeroed in on a very specific range of powder weights that seem to be very tolerant of slight pressure variances.  You can see the previous posts for how I got here. My next step is to test 5 shot groups in very granular powder increments. Jump to another step: Part 1: Bullet Selection & Real-World Velocities Part 2: Audette’s Ladder Test Part 3: Optimal Charge Weight Part ...

7mm Rem Mag Chamber Print

When the 7mm Remington Magnum was originally released, it was met with overwhelming demand.  Every rifle manufacturer rushed to offer rifles chambered for the new cartridge, and in the rush some of the chamber dimensions varied slightly from different manufacturers.  This variation in the 7mm Rem Mag chamber dimensions has carried on to today, and there is still more differences in the chamber dimensions than for virtually any other rifle cartridge. What’s a chamber print? A “chamber print” is an illustration of the chamber reamer used to cut a rifle’s chamber.  It contains all of the key dimensions related to ...

7mm Rem Mag Load Development Part 3: Optimal Charge Weight

After I identified a promising range of powder weights using Audetter’s ladder test, my next step was to use Dan Newberry’s Optimal Charge Weight (OCW) Method to offset the “scatter node” drawback inherently present in the ladder test.  To learn more about that, read this article comparing the OCW method with the ladder test. The OCW method is based on the observation that there are some loads out there (like Federal’s match ammo for the 308) that shoot really well out of just about any rifle.  How can one recipe shoot so well out of so many different rifles?  Dan Newberry believes accuracy of ...

7mm Rem Mag Load Development Part 2: Audette’s Ladder Test

The first step in load development for my new custom 7mm Rem Mag started with gathering the real-world velocities I could expect out of three quality long range bullets I was considering. I then used those velocities to compare the ballistic performance between those three bullets, as well felt recoil during the test rounds. I eventually decided to pursure further load development for Berger’s 168gr VLD bullet over Hodgdon Retumbo powder because it struck the right balance for me between the competing characteristics (recoil, barrel wear, flat trajectory, low wind drift, ideal energy for medium sized game, etc). For more ...

7mm Rem Mag Load Development Part 1: Bullet Selection & Real-World Velocities

The first step in load development for my new 7mm Remington Magnum (with a 27″ barrel) was to get a basic idea for the real-world muzzle velocities I could expect out of a few different high quality, very low drag bullets, so that I could compare them ballistically and decide which to pursure for further load development. I decided to try out the three bullets listed below after reading a great article on 7mm bullets by Nathan Foster. I actually took all of these readings with a BRAND NEW BARREL (some of the first rounds out of it), so they ...
