Rich, I took the time to read thru this long thread and it made my head hurt. Some of the information you have received is good but a lot is not. I have been shooting the M1A in competition since the early 1980s and have learned what works and what does not work. If you have your problems solved then press on but if you are still having problems and would like my help send me an email at chkunz@bellsouth.net. Best wishes, Clyde the elder.I need help. My reloads are not cycling smoothly. About every third shot theyre either not extracting from the chamber or are not fully seating against bolt. I am not having this problem with store bought ammo. My loads are once fire lake city brass, hornady 150 grn fmj's, 42.4 grns IMR 8208 XBR, and remington 9.5 large rifle primers. 150 grn Hornady fmj's are loaded per HOrnady manual data, not the service rife data, I couldt find the exact 150 grn data in the service rifle section. Guns up bro's, semper fi.
Ive only been reloading for 9 months so any constructive criticism is greatly appreciated.
