[QUOTE="nicholasjohn, post: 1612596, member: 109113"] I have a 30-06 Ackley Improved, and the guy who built it put a 26" barrel on it, even though I had told him I wanted 24". It was close enough to hunting season that I just used it that way, and had him shorten it later. So, I had the rare opportunity to shoot a rifle with both a 26" and 24" barrel, with everything else being the same - same load, same barrel, same chamber, same chronograph, etc. The only change was taking two inches off the barrel, and velocities dropped by 100 feet/second. I had expected 25-30 fps/inch, like I had read in numerous publications. NOT SO - it was a full 100 fps slower, and accuracy was the same ( excellent.) So, don't believe everything you read about barrel length vs. velocity. Try it if you don't believe me - you may not get what I got, because there are other variables in the equation. Some of those variables we don't even know about. But that's what I got. With your .270 Ackley, you will quite likely be glad that you went with the longer barrel, especially if you're building it on something like a falling-block single shot action. This will enable you to have a longer barrel on a rifle with the same overall length, due to the shortness of the action. I've worked with that concept, too - and have been pleased with the results. A 26" barrel is kinda cumbersome on a 30/06-length bolt action, but not on something like a Ruger #1 or Dakota Model 10. ( The Rugers are heavy; the Dakotas are not.) Anyhow, have fun with your .270 Ackley, and with 26" of barrel, you will probably find yourself feeling like you've got a .270 Weatherby. You may want to lean toward the slower-burning powders for that cartridge, since you have he barrel to burn it in.
