I personally love CCI standard velocity 40gr lead round nose for an all around decent shoot. When I hunt, depending the game in question, I will use a few different types, for larger game in close I like Aguila 60gr SSS, in testing they penetrate 20" of ballistics gel at 25 yards, I have killed small hogs with these, mind you I was a **** of a lot closer to that hog than I ever want to be again, a was a little hair raising to say the least, for smaller game in close I like pretty much anything in 1000 fps range, with a lighter bullet say about 32-36 grain, for anything farther out than say 60 yards I prefer the higher velocity stuff Aguila makes 30 gr bullet that they push at about 1700 fps, these as well as the CCI stingers are awesomely devastating at ranges beyond 60 yards. I'm still in the testing phase to be honest these are just a few that I have found that work well in my Marlin and my Remington, again, I'm still trying to figure out what I like as well as what the guns shoot well.
