in a 243, 22" barrel 3358fps. 26" barrel 3614fps, 240 why, 26" barrel 3872fps

that's stepping right on out there. I guess there's no worry on running them too fast, then...



I know a couple of guys that run them out of the 6mm-06. dont know there fps but it should be about the same as my 240 wby
