How much are you jumping the 140 Bergers?I absolutely love my 260 Rem! My bbl is a 1:836 twist. I have quarter MOA loads for all my loads from 120-142 gr!
I compete and hunt with this rifle.
All my loads are with H4831 SC or H4350.
I measure all loads off the ogive. My bullets I use consist of Barnes 120 TSX, Berger 140 VLD, SMK 140, Hornady amax and ELDs 140 gr, and Nosler 142 LR AB! Get you one is awesome!
