I like a 1-8", or 1-8.5" for the 140's. You will have problems with stabilization in sub-zero temps with 140gr bullets with a 1-9". I'm not throwing out a guess, I've seen it. A 1-9" will champion the 130's like a dream in any temperature or elevation. Thats the bullet I like in .264" for cases the size of 6.5 Lapua, .260 and 6.5X55.


Luck....is the residue of design...
