I have a Remington Sendero that I have rebarreled in 300 RUM with a 28-inch Krieger. It has absolutely dumbfounded me with its accuracy at 100 and 500 yards. I haven't had access to longer ranges yet. My last three three-shot groups at 500 have been 1.54 inches, 1.96 inches and 2.8 inches. I am shooting 94 grains of Retumbo and have had it on the chronograph in October and in January. In October, it was averaging 3,175 with single digit ES and SD. In January, it averaged 3,152 FPS with low double digit ES and SD. When shot in October, it was 87 degrees and in January 47 degrees. I'm very curious what velocities others are getting when using the 210 Berger. I'm not talking about what velocities you can attain just as the bolt locks up, but I'm asking what velocity you are getting loaded for accuracy. Thanks for your input.
