G-ManBart Posted January 19, 2010 Share Posted January 19, 2010 (edited) I loaded up some 124gr fmj with 4.8grains of power pistol and the c.o.l is 1.150. and its coming out of a g17. any idea what pf it will be? Do you have a reloading guide? Doesn't look like it will make Minor from the data I have. Hornady data shows a 124gr FMJ with 4.7gr of PP coming in at 950fps. You're going to need over 1000fps, and realistically 1050fps to get a cushion (130PF). The book says that will take 5.3gr of PP at the same OAL you're using. Sierra's data is a bit different. They show 4.7gr giving 900fps and 5.5gr to get 1050. Looks like you're probably in the 115PF range give or take a bit.
