Thanks for the additional info!
When I've run my own cold-tempeature tests, I've tested cartridge/bullet combos that are very well suited to the powders, such as TAC and Benchmark with 50-grain bullets in the .223, or H4350 and Hunter with 100-grain bullets in the .257 Roberts.
John,
There hasn't been much mention of Benchmark, and I'm using it in my 358 WSSM - how does it compare vs TAC with regard to temp insensitivity?
Thanks!
