I have new lupy STD rings for my win ation. Is it REALLY that important to have the rings lapped? The scope I will be getting lupy 6.5x20 long range will get me to 1k. Im shooting 300 wsm. Keeping factory 24" barrle for now. If I get heaver longer barrle later for more speed, distance then I'll get tapered base and bigger rigs. Just trying to save pennys where I can.
