Hunting season has ended and shooting season has begun where I am at! I have a 300 RUM Sendero, stock 26 inch barrel that is capable of sub moa out to 1000 yards if I do my part. My load is 92 grains of Retumbo, 215 Bergers, Rem brass, Fed 215 match primers, 3.690 col (can fit one in magazine), and it chronos at 3100 fps. Velocity seems to be in line with what most folks are posting. (I know, everything on the internet is true) The only pressure signs I'm getting are flattened primers. No sticky bolt lift all. My question is this....Should I back off until primers quit flattening or keep this load? What would you do? It's scary accurate and I'm somewhat hesitant to change. I have 48 pieces of 2x fired brass tumbling right now. Going to give the gun a good a cleaning, shoot my final two rounds as foulers and either duplicate the load posted above or change it up a little as time allows.
