[QUOTE="Veteran, post: 2755135, member: 118038"] Go to Varmintal.com Look on the left hand side at topics, select light rifle with tuner [URL unfurl="true"]https://www.varmintal.com/alite.htm[/URL] At the bottom of all this analysis is a little gem, here's the heading. [B]Barrel Length vs Accuracy & Muzzle Velocity What he shows is that for .223 caliber the best accuracy is for 17 inches or so. But the curve is flattish out to about 22 inches, so you can go 22" to get more velocity without losing a lot of accuracy. So, 22 inches is fine for hunting for sure. His analysis also shows as you would suspect different accuracy for different bullet and powder combinations. But not dramatic difference in optimum barrel length outcomes. This analysis may differ some with higher magnum calibers and slower burning powders. This site offers great insight into the whole science of barrel harmonics. [/B] [/QUOTE]
