Yes, I have a 7mm WSM on a blueprinted Rem 700 SA with a 30 1/2" PacNor Select Match Grade. Sits in a Choate Ultimate Sniper stock, but I'm thinking about getting a McMillan. Using a Millett LRS 6-25x56. Not the most high end scope there is but it has given me no problems whatsoever, besides being a pain in the A$$ to buy scope rings for being a 35mm tube. A buddy and I shoot out on his farm out to about 1,200 yards. I just have the urge to stretch the limit. This build is for pure fun. What direction would you take on a .375 build for long range then? 9.53 Saturn or .375 RUM? The .378 Ackley Mag sounds promising also. This build won't start til next year but I'm starting to get parts now. Your input is very very helpful.
