How will barrel length affect fps in bolt action rifles? I know in aegs, a full size (non-ported) cylinder will achieve the best fps with a ~480mm barrel. But what is the optimum barrel length (regarding fps) for snipers (VSR10 and APS2)? Because bb weight and spring power will also affect barrel lengths' relation to fps, lets just say that a 500 fps (w/.2g bbs) gun is shooting .36g bbs. Also, does having a longer barrel and a larger cylinder help when shooting relatively heavy bbs? Does anyone have any data regarding barrel length vs. fps? Thanks!
