Re: 210 Berger in the 300 RUM?
Ditto on the 94 grains of Retumbo and 210 Berger .010 into the lands. Three-shot group at 500 yards measured 1.963 inches. I had to go to the Winchester Large Rifle Magnum primer to get my chrono numbers to settle down, and, boy, did they ever. The numbers were 3,173, 3,175 and 3,178 for a 5 ES and a 2 SD. I cannot wait to get the crosshairs on a deer somewhere between 600 to 880 yards. The barrel is a 28.5 inch Krieger with one of Danny Huffman's muzzle brakes screwed on a Sendero action and stock.
