Had a discussion that got me thinking more about this subject. I've been going to and fro on Varget and H4895 in my 308 bolt guns. 4895 has given a SD of 7 on a particular load. I've been using 4895 since the 70s in 308 and 30-06, hunting in temps down in the 20s and I've not had any issues. In the Battle of the Bulge and the Chosin Reservior campaign in Korea, temperatures were Zero to -30F. The M-1 Garand and the Browning 30 Machine operated fine on the 4895 powder loaded in the 30-06 cartridge.
I was visiting with a target shooter who tells me that I'm going to have trouble with CFE223 in my 6.5 Grendel, recommending XBR-8208. I'm not a target shooter, so I'm not worried about my .2" groups going to .5 or 1" in colder weather. I haven't chrono tested in cold weather, but will do so. I would appreciate any thoughts.
