The Black Diamond is one of the best shooting rifles I think Thompson Center ever made. Mine will shoot about anything you shove down it. 100 grains of powder and a 250 grain Shockwave will give you "normally" excellent results.

Things to watch is the breech plug. After ten shots, take your breech plug wrench and give that thing a twist back and fourth to make sure it is not seizing up. I tell you this from experience as no one warned me... Other then the bad fowling of the open breech design, there really is not a better shooter out there in my opinion.

With loose powder, start your loads at 80 grains and work from there. You have a 22 inch barrel, so there is no reason to shoot anything over 120 grains of powder out of it. I like my rifle, but seldom shoot it. Because you take it to the range and it loads the bull with hits, you take it home, clean it, and the next time to the range it is the same thing all over again....

We are having a major storm here as well. Lots of wind, snow, almost a blizzard of sorts.. I got the yard cleaned already (approximately 8-10 inches) so the rest of the snow will be easy to remove...
