Re: Barrel lenght
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: iceshooter</div><div class="ubbcode-body">Im a bit unsure about the effects of barrel lenght. If we simplify things quite a bit I understand that most centerfire rifles need a barrel near 22-24" to be accurate enough. Why did the Remington xp100 do so well with only a 10" barrel? </div></div>
The handgun silhouette crowd who were shooting those XP100's had done copious amounts of load development to find a load that burned most of the powder in a 10 inch barrel. Depending on the chambering - in the original XP 100's, the 221 Fireball - 10 inches may be enough pipe for the powder to burn efficiently. Once you try larger capacity cases and chamberings, a longer barrel will be needed so that you aren't spewing unburned powder out of the muzzle. All other comments on rigidity, etc. also apply.
