Anyone using Hornady's 139 BTSP in the 7-08 with H4350 or Varget?
I used to use the 139 Interlock and h4350. My load was near max and shot really well. Most manuals top out at about 46 grains of H4350, but Mule Deer says that the 139 IL has a shorter bearing surface and can handle up to 50 grains. My best accuracy was about 48 grains, so I stopped there. Then I went to Big Game and 120 BTs and haven't looked back.
