123 amax versus 140 amaxs

[summitsitter]

Will I be able to tell the difference at 600yd. I'm building a 260 with a 1/9 twist Shilen select at 26". I was wondering which will do better or if I'll even be able to tell. Would like to set the throat up for one or the other.

I have not shot any of the 123 AMAXs yet since I shoot the 123 Lapuas in my 260. However I used to shoot the 140AMAX in my 260s and have now gone to the 123 Lapuas in my 260s.

I think its the perfect bullet for the case size. I always felt the 140 was a little on the heavy side for the 260 sized case esp after shooting the 6.5x284s. The 123s in the 260 is like shooting my 6.5x284 now. I would not worry about throating one way or the other. All my 6.5s have liked some jump.
