I have used Weaver or T/C bases with Weaver style rings on all my Encore and Contender barrels with no problems what so ever. In addition ro functioning well, they are readily available, inexpensive, and very simple and straightforward to use. What more could you ask? I do not have any "big bomers". 25-06 is probably the heaviest recoil I have, mostly varmit-type cartridges.
Aim Small, Miss Small!!!
