[QUOTE="3006savage, post: 343342, member: 12069"] I read an article a few years back that took a 7mm 08 with a 26" inch barrel and shot 10 rounds (I believe) and averaged the velocity and then cut 1" off the barrel and recrowned and then shot 10 more and averaged etc. They went down to like 18" one inch at a time. I remember doing the math in my head and it worked out to just 17 fps per inch velocity loss with the largest losses comming as the barrel got shorter. Even getting down below 20 inches the losses were only 25 FPS or so. I had always believed that the losses were much greater and that article changed my mind. I really liked this evalution because it was from the same barrel with the same ammo so that variable was eliminated. I would personally go with a 22" barrel if it is a carry rifle. [/QUOTE]
