[QUOTE="7magcreedmoor, post: 1101494, member: 48559"] Two barrels don't make for a statistical sample, but as an anecdotal example, I could not get more than 2870fps out of my 24 inch 7 rem mag (factory barrel) with the bullet I preferred. I had it rebarrelled with a 26 inch tube and was able to run 3050 using the same bullet and charge. I know there are more variables in play here than just length, but my 6.5/284 hits 3020 out of 26 inches, and my 280 AI runs 3015 out of 26 using the same bullet as my old 7rem mag, but using much less powder. If you want downrange energy, you have to have the velocity leaving the muzzle. Decide how far you need to deliver how much energy, and cut the barrel to whatever gets it done. This discussion reminds me of that joke about the young lady insisting that she wouldn't marry a man with less than a certain length "equipment", and after consulting his doctor he assured her it could be trimmed to whatever length she was comfortable with.... We could have the same discussion about girth.... [/QUOTE]
