Need help determining proper information.
I am loading 9mm with 124gr Montana Gold FMJ with 4.6gr W231 at OAL 1.160I was using Federal Primers. Shooting a STAR 30M 9mm.
Yes i used load data, confused on old vs new data, shows a difference in max.
I was attempting to get minor PF.
My old Lyman 48th showed a Max load for 124gr at 4.5gr. Some of the older Winchester load sheets did also. Recently, i have started seeing the max load data showing 4.8gr for W231. The Hodgden online shows only for a 125gr FMJ, but gives the 4.8 max load. Also i have seen in other manual (I should of bought a new one) the 4.8 is max load.
My concern is related to the attached pictures, Can someone tell me if they see overpressure signs on the primers? I think that the signs are there, but again dont know if its overpressure or something else.
I chronographed 35 shots today and had an average of 1063.7FPS with a SD of 10.502 and showing 310FP and a average PF of 139.91.
I dont think that this is max for a 9mm, but i could be wrong, anyone have any comments on this load. Is the new load data incorrerct?
Thanks
