That is a great bullet on game, but unfortunately for me it gave shotgun patterns out of my rifle. Lastly you might try going with the 100 gr Barnes TTSX. That is a great bullet that you can drive really fast and flat. On the other hand they are almost twice the cost of a cup and core bullet.
Best load I came up with for that powder: 117gr BTSP Hornady, Win brass, IMR 4831 near max, CCI 200. This one shot 3/4" out of a factory Mod 70. Don't bother with primers until you find the bullet your gun will actually shoot. Once you find that then you can tweak the load.
Thanks for this info. I really do want to shoot the Barnes for two reasons. First, I am retiring from active duty in the next two years where I will be relocating back home to California which is in a lead free state. Second, this strictly a medium game hunting rifle and I have been told by several people that the barnes are awesome on game. I tried the 80 gr barnes and that didn't work. I want to try the 100 gr but I was worried about stabilizing them as my barrel is only a 1 in 10 twist at 22 inches. At $36 a box its a little unnerving to keep throwing money at something without hearing from others that they have had success with that certain recipe.
