[QUOTE="Lefty7mmstw, post: 903609, member: 48043"] I've never seen more than 25 or so fps per inch between bbl's and it usually varies. I'm not saying your#'s couldn't happen, but they would more than likely be due to fast bore/ slow bore differences than anything the bbl. length is actually giving you. You can't actually compare two different rifles here; you have to actually cut down the barrel you are testing as every bbl. is different. I've seen some of the loads actually put up faster #'s with the 24" bbl's than the 26". You are at 10,000 psi (about that of a shotgun) at the muzzle end here so you aren't getting a heck of a lot per inch anyway. [/QUOTE]
