Web Blast: Wildcatting

Hunting M/A 2010

Left to right: The .222 Rem., .223, .222 Rem Mag., .20 tactical, .204 Ruger and the
.222 Mag JDJ. The JDJ round chases the .22-250 in performance with some loads.

Selecting barrel length is often a major problem for the average shooter. The vast majority select middle of the road length barrels but the trend of questions about length often revolve around extremely long barrels for both pistols and rifles.

The expectation of what a long barrel will do versus a short barrel is often unrealistic in both velocity and accuracy. Having spent thousands of hours and hundreds of thousands of dollars with a large variety of calibers and chronographs, I’ve come to some general conclusions. The final assessment? The the more I know the more unanswered questions I have.

For example, in revolvers, single shot pistols and rifles the length of the barrel is of little or no consequence ballistically in hunting guns. The barrel length will not make any difference to anything you shoot. Excessively long barrels may be counterproductive to accuracy and velocity. Yes, there are “fast” and “slow” barrels and in some cases I can see the reason, but in most I can’t. Types of rifling, chamber dimension, throat and other factors all contribute.
