A friend asked me to help him reload some Win 243. He purchased the dies, primers, bullets and powder a while back but didn’t have the confidence to do it himself. I have loaded shotgun and pistol for years but I haven’t done rifle in a long time. He has the RCBS 2 dies set, full length sizer and Winchester Supreme 780 powder and 100 GR bullets, I think Hornady 2453.
Does anyone have any advice? I have the books and load recipes. All brass is once fired from his gun. Does rifle brass normally need trimmed after the first shot?
I've read that 243 doesn’t really need a crimp, anyone else agree?
Thank you for your input,
