[QUOTE="shocking300, post: 807923, member: 41276"] I have shot thousands of 300wm rounds, someone said to try norma brass, so today ran it through chrono and same charge it was 150 fps slower , it was new and not fireformed. Is that normal ? My understading is norma has less volume so higher pressure to be expected with same charge. 300wm The load is 74.7 H1000, 225HPBT Vel 2610fps with norma, winchester 2760fps same charge. Thanks [/QUOTE]
