RE: Rifle build,which caliber?
Ordered 200 rounds of brass (same lot #), sorted cases by weight, trimmed & turned necks, uniformed flash holes, annealed, etc. Ended up with 71 rounds of matched brass and have the others segragated into 2 other batches. On the third reloading with these cases, haven't had any problems yet with split necks, swelled primer pockets, or head case separations, etc.
Yep Remingotn brass is not my first choice of brass for any of my rifles, especially in my wildcats, but in this case it was the only brass available in 7mm RUM. Not trying to convince you of anything. Been reloading for far tolong, withmany hundreds of thousands of rounds reloaded myself, for that.
