Good shooting, I think, I've never shot with a peep sight. Also, I've never heard of a 365 grain Maxiball, did you cast them yourself and are they .50 calber? I can get the .50 caliber in a 320 grain and a 370 grain, but I've never seen a 365 grain maxiball. Not much of a difference I guess. I don't like shooting them anyway. They kick too much. They sure do a number on a whitetail deer though.
