[QUOTE="Stokesrjsr, post: 2846466, member: 108548"] I have preferred the Federal 215 GM for a long time and they are a truly a great primer. However due to uncertainty of supply I’ve been forced to substitute the CCI 250. But I spite of my personal bias, I can detect no discernible difference in standard deviation or precision in a 300 meter test tunnel with an Oehler 85 ballistics laboratory. Either can achieve ES of 15 and SD of 5 or less, using new Lapua Cases, Berger bullets and Vihtavuori powder. 1000 yard groups of 1/2 MOA under favorable weather conditions is achievable with either.
