I use Imr 4895 in .223, 308. 3006 and 7.62x39 and I tried it in 7.62x54r when I was trying to get it to shoot decently. If I can't get that then I try to find H 4895 or Varget. They are all so close together in burn rate it really doesn't matter. the only rifle cartridge that gets anything else is the M1 Carbine and I use WW 296 for them. All pistol cartridges get a dose of WW 231 from .380 to .45.
