With breaking in the barrel on a Cooper M22 in 243 Win. I tried a load using R 19 with a 70 gr Ballistic Tip.

I know one group isnt enough to go by but this 5 shot, 100 yard group shows promise. The other 2 powders I tried didnt do as well.

I only have 15 rounds through this rifle and will try tweaking this load a bit and see what happens.
