Tag Archives: Rifle Group Size

If you only read one article in this series, MAKE IT THIS ONE! This article takes all the data collected over months of live-fire research and sums it all up by ranking each type of ammo by hit probability from 400 to 1,200 yards! After all, the size of a group on paper at 100 yards or the muzzle velocity our chronograph spits out doesn’t really matter – at least not directly. For long-range work, all that actually matters is if our bullet impacts the target downrange. Precision and velocity affect that, but so do a lot of other factors! So this article is like the grand finale and ranks which ammo gives us the best odds of connecting with long-range targets.

Welcome to Part 5 of the results from my massive 6.5 Creedmoor ammo field test! This article will cover the results from over 150 five-shot groups that I fired. There were 760 shots for record, which I carefully collected over several tedious days at the range. When it comes to long-range, precision rifles, many of us can fixate on trying to coax tiny groups out of our rifles. After all, if you can’t hit a 1” target at 100 yards – your odds of hitting a target at 1,000 yards aren’t great. But, what is factory ammo truly capable of? ...

This is the final article in my Statistics for Shooters series, and it focuses on the application of statistics when it comes to quantifying precision and group size. It provides practical answers to some age-old questions: How many shots per group do I need? Should I exclude fliers? Is extreme spread the best way to measure my groups? What is the most effective and accurate way to compare groups between two loads? I spent more time writing this article than any other single post I’ve ever written! It challenges some common beliefs held by some in the shooting community, so I tried to carefully present the reasoning behind that in a way that was approachable to shooters who aren’t math nerds. It also contains a lot of practical tips. I firmly believe these concepts will help a TON of people in the long-range community.

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 them 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 ...

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 ...
