Very interested in the rifle. Wouldn't need the brass since I'm a newbie to hunting and don't reload...and with 3 kids under 8 in the house I lack the time! I'd be taking my SHV off my current rifle, does this come with rings? Dumb question, with your load data can I order ammo from GW or another company. Hunting is new to me and I'm just learning. This would be a "lifetime " rifle!
