Red
I once had a #1 458 and now have 2 350 Rem Mag ^00 carbines. I also have a 2.5 Weaver that has been used on all three rifles with no problems. I think the recoil is much sharper with the 350 Rem. I also have one of the first $10 4x Tasco which the dealer said he would replace if I could shoot the cross hairs out of it. It is as clear as anything I own and still going. It also has been on all three rifles. I have always used Redfield bases and rings when possible so nothing moves. Ruger used the rings that came with the gun. I now have a Burris 4x12 compact on one of the 350s It has become one of my favorite cast bullet guns. Recoil no longer an issue. Scope is only as good as its service go with one you can get fixed. Have you considered a receiver sight?
