[QUOTE="killahog, post: 144994, member: 3722"] Old bear Have you actually shot the 25-06 over a chrony or are you using an estimation for the velocity?. I have a 25-06 AI and I am going to try some 75g vmax next week however I have talked to 2 others who have had those bullets blow up before reaching the target at velocity above 3800 fps. I have also used the 115 berger vld's and Hit a prairie dog @ 1100 yards But the little rat made it to its hole and I could not confirm it was killed. I now for a fact though I hit it and I also had a witness that saw it. Just for the record it took me 21 shots to hit him. I have also talked to Dan about the rate of twist vs velocity and I believe the biggest factor is not variance of barrel's but it would be the bearing surface of the bullet, 75g bullet as opposed to a 100g bullet one would speculate a 25% decrease in friction although I am not sure how much more friction would be added by a slower twist.
