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 ...

How Much Does SD 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. There are so many variables that it’s easy to get lost, and most of us end up doing our best to spread our ...

How Much Does Group Size Matter?

As long-range shooters, we tend to obsess over every little detail. We think everything is important! After all, we’re trying to hit relatively small targets that are so far you may not even be able to see them with the naked eye. While you can get away with a lot of minor mistakes and still ring steel at short and medium ranges, as you extend the range small mistakes or tiny inconsistencies are magnified. So, most things are important … but to differing degrees. So if we have a limited amount of time and money, where would we get the ...

7 Ways the New ARC Rifle Action Blends the Best of Old & New

Ted Karagias of American Rifle Company (ARC) wowed us last year, with his fresh and innovative complete rifle system and an action, earning the title of Most Innovative Product of SHOT Show 2014. Now his Mausingfield Action has officially made it into production, and is available to the public. It received a lot of attention at SHOT Show 2015. A few weeks ago, Ted sent me action serial #00001 to test, and I used it to fire hundreds of rounds of Hornady 6.5 Creedmoor Match Ammo. Here is a quick video that highlights some of the features of ARC’s Mausingfield Action, and ...

Reloading Components – What The Pros Use

This post reviews the reloading components (bullets, brass, and gun powder) the best precision rifle shooters were using in 2014. The data is based on a survey of the top 50 shooters in the Precision Rifle Series (PRS). The PRS tracks how top competitors place in major rifle matches across the country. These are the major leagues of sniper-style competitions, with targets typically in the 300-1000 yard range. This is the 3rd year we’ve collected this data. For more info on the Precision Rifle Series and who these guys are scroll to the bottom of this article. Long-Range Bullets Here ...

Tactical Scopes: Field Test Results Summary & Overall Scores

This is the executive summary and overall scores from an epic scope field test focused on long-range, tactical rifle scopes in the $1,500+ price range. This represents an unprecedented, data-driven approach to evaluating the best scopes money can buy. Over 400 hours have gone into this research, and the line-up and tests are built on advice from some of the most respected experts in the industry. My goal with this project was to equip fellow long-range shooters with as much hard data as I could reasonably gather, so they could see what they’re paying for. I’ve published ridiculously exhaustive details, ...

Tactical Scopes: Mechanical Performance Part 2

The previous post contained the details of the mechanical calibration test, which I think was one of the most enlightening tests of this entire field test. This post reviews several other tests I ran related to mechanical performance, including: Scope repeatability and whether it could reliably return to zero Reticle cant Reticle calibration Max internal adjustment range (i.e. elevation travel) Elevation travel per revolution Windage adjustment range Magnum recoil box tests Lots to cover, so lets dive into the results. Repeatability & Returning To Zero The setup of this test was identical to the click calibration test I covered in Part 1. Instead of ...

MIL vs MOA: An Objective Comparison

MIL vs MOA Comparison Article

There are a lot of articles and forum threads out there comparing MIL and MOA, but most either aren’t objective or they’re overly complex. I’ll try to avoid both of those pitfalls in this article. Executive Summary A few months ago I asked Bryan Litz whether he personally used MIL or MOA. Bryan is an expert among experts in the shooting community, and after reading his books I’ve gained a respect for his scientific approach to decisions like this. His response was so concise and objective, I thought it could serve as the executive summary for this whole comparison: “You ...

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 ...
