[QUOTE="QuietTexan, post: 2065671, member: 116181"] This isn't a large enough group to be statistically relevant, but it was so odd I knew where to find it in my notes. 300 RUM, Nosler ABLR 210gr, WLRM primer, 81.0gr IMR 7828SSC. COL / FPS (avg 5 shots): 3.543 / 2800 (.125" off lands) 3.596 / 2805 (.072" off lands) 3.628 / 2814 (.050" off lands) 3.658 / 2823 (.010" off lands) The hidden detail here is that each of the ES ranges overlapped with at least the seating depth above/below it. The averages just make it look like it's moving up with the bullet out further. The whole string was ES 39, SD 13, which is not too good. [/QUOTE]
