Thread: Barrel Lengths and Accuracy

The answers are all anecdotal. the only way you'll ever know would be to do a proper experiment, and why would you when most rifles be it 16" or 32" will go sub MOA

Regarding 22lr, the most accurate bench rest rifles are built with about 24" long tube and they use muzzle tuners.
Yes the 22 bullet needs only 16 to 18" to burn all its powder, but the longer flexible barrel makes barrel tuning much easier.

By the way the reason tuners are used with 22 lr, is because the amo can not be tuned by hand loading, the variation of speed between each bullets is compensated by the different angles positions the muzzle takes when releasing said bullet, so that they all end up on the same area of the target.( hope that makes sense)
