[QUOTE="Trickymissfit, post: 431116, member: 25383"] I seriously doubt you'll see 100 fps loss in velocity if you go with a faster powder burn. But what you will see is a stiffer barrel (I thinking 24" barrel here), which will aid in shot repeatability. Here's something to think about; with a #7 contour barrel 26" long (that's a pretty heavy barrel) verses the same exact barrel 21", the 21" barrel is right at 2.75 times more ridgid. So in theory you shorld see a little difference just cutting the barrel off two inches. You still should see close to 3100 fps (safely) with a 180 grain bullet and a 24" barrel. I'd also say that you'll probably see close to 2950 fps with a 22" barrel and the correct powder burn, but will probably group even tighter. gary [/QUOTE]
