A question for reloaders of .300 short mags: What issues have you encountered when trying to develop consistent loads for the short/fat mags and how did you overcome them? Background: I spent the better part of 2 years trying to develop an accurate load for my 700 BDL in .300 SAUM. Different bullets, bullet weights, powders, powder weights and seating depths were tried. The bullets were what we would all recognize as "premium". The powders were all respected brands. I was just about to give up on the rifle. Eventually, even a blind sow finds an acorn and I did too, but it was 300+ test bullets into the work. I was finally able to get a 165gn TXS seated at 0.070" off the lands to give me a sub MOA group with less than 9 fps standard deviation in velocity. The powder is IMR 4350 and the primer is a Fed 215. I don't want to go through this again and if you have any advice / tricks specific to the short mag, I'd sure like to hear it. PS: I also load .30-06, 7mm Rem Mag and .22-250 and have never had difficulty developing a consistently accurate round with any of them.
