My 7mm is at the gunsmith. When I get it back I'm going to mount my Vortex HS 4-16x44 on it but I need some suggestions for rings. I'm looking to make it a 600ish yard big game rifle. The gun shop carries Leupold, Vortex and Weaver rings. The rifle has some weaver bases on it right now. I've only been reloading and shooting religiously for a couple years now so I don't know much about good rings. Any input/suggestions?
