300 Norma Mag Custom ELR Rifle

300 Norma 338 Lapua Custom ELR Rifle

I’m sharing a series of posts on ELR shooting, but I didn’t want to jump from the long-range rifles in mid-size 6mm and 6.5mm cartridges that I normally talk about straight into the extreme, super-high-performance 375+ caliber rifles used to engage targets at 2+ miles. Instead of just presenting the extremes, I thought it’d be helpful to first share a rifle setup that is somewhere in between. Then in later posts I’ll get into the more specialized setups used to push the boundaries of what is possible with shoulder-fired rifles. In this post, I’ll share the details of a rifle ...

Muzzle Brakes: Recoil Results for 308 & 300 Magnum

308 Muzzle Brake & 300 Mag Muzzle Brake

This post summarizes the results for the recoil tests ran on 20+ muzzle brakes using two 30 caliber test rifles: the 308 Win and the monster 300 Norma Magnum. The recoil data was collected using high-speed, high-resolution force sensors. For more info on the test equipment and how the data was gathered, please see the recoil post. Here is the full line-up of muzzle brakes, and you can read more about each in this post. How to Read the Results As we discussed in the recoil post, when someone claims a product “reduces recoil by 50%” … it usually isn’t ...

How Much Does Muzzle Velocity 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 ...
