Savageshooter--
I have several sets of the Warne rings and 1 set of bases and they are hell for stout...I used the bases on a M7 I had. The rings adorn several of my LR/Varmint rifles and I also have a set on a .308 PSS and a set on my custom .338 RUM. They hold the heavy scopes well without spending a fortune. I recommend the Maxima line of rings( either the TPA or the Lever-QR style) and the Ken Farrell tapered bases.

For the money, this combo can't be beat for toughness....
