I've been working with my .40 Virginia build and was having issues with holes in the patches, a thicker patch cured that. Since the load I was shooting, 45gr of FFF was worked up with the thin patch. Today I set the bench up and went through load testing again. The rifle was built to shoot offhand, but all testing was done from a bench with a front rest and rear bag. I started with 40 grains and worked up to 60, 55 was the best. I'm on my last tin of Remington caps, after that it'll be CCI's. I didn't think about it until I was halfway through, so I finished the tests, then went back to the best charge and shot the CCI's. I may do a little more testing around 55 grains just to see what it does.
