Leupold (pronouced LEW-POLED) has tapered 1 piece bases - which use Lew-poled STD rings - tapered about 20 MOA so you get 20 MOA more elevation. Avail for Rem 700 long and short actions. Only $21. The Std Rings are ( 30mm for my scopes ) are only $33 pair. I know the Lew-pold QRW rings aren't good for anything larger than a .22 rim fire (OK, maybe a bit bigger - but they won't hold up to heavy hitters). I have 3 new RUMS (300, 338, 375) which I'm having Kirby install a Holland QD break on each. I will lap the rings with the SInclair Scope Lapping kit. Finally the #$%^ question. This set up is so much cheaper than any other tapered base/ring set up I've looked into - will they work for my RUMS (given the Holland QD break will really soften the kick)? The guns are each getting a Lew-Pold VX-III, 4.5x14 50mm scopes (30mm tube as mentioned). I like the idea of going all Lew-Pold - the low price is a bonus if it works.
