I'm getting back into long range shooting again, been quite a few years. Bit the bullet and bought a browning M1000 eclipse in 300wsm. I don't know why I was concerned with recoil, heck, I shot 25 rds in one hour with no problems. very accurate rifle. Back to the question. All of the ballistics I have found for the 300wsm have been based on the 24" barrel. I would like to find the ballistics with a 26" barrel. As with the weatherby 270 and 26" barrels, as opposed to the winchester 270wsm in 24". There should be a difference. Can anyone point me in the right direction?
