Re: 300 RUM, 200 AccuBond + Retumbo Results:
Finally got a chance to do some more load testing and am really happy with the Accubond results. I've settled on the 200 gr Accubond with 95.5 gr of Retumbo and a Federal 210M primer. Iw as getting too much extreme spread with the federal 215's.
This load is giving nice little cloverleafs at 100 yards(under .5" ctc) and clocking 3199 fps at 15' from the muzzle over an Ohler 35P. I hope to try it on an Antelope in the next week or so in Wyoming....
