I have a Bushmaster (A-2). It shoots the 62g HP Silver Bear stuff pretty daggone good. It's got some kind of copper washed metal jacketed bullets(not copper, maybe tin), but it's a fairly soft jacket, so I don't think it'll hurt your rifling.
This ammo knocks a pretty good sized exit on a groundhog out to around 200 yards, so I wouldn't use it on a pelt.
It's hard for me to say "exactly" how accurate it is in this rifle because I mainly just plink with it. I can tear a pop can up at 150 yards with the "almost" stock sights. I turned the front post down, then re-flattened the sides so I have a finer aiming point. I figure that's plenty good enough accuracy for this particular rifle.
I tried some wolfe ammo, but it wasn't very accurate at all, and the coating on the cases gummed up my chamber, and made manual extractions very hard. It was a pain to clean back out of the chamber too.
