Needing help on my 9mm loads
I am shooting a H & S 147 FP coated measured at .356
3.2 g TG
velocity 943 +/-
Crimp diameter is .380 and oal= 1.068 which is just off the lands passes plunk and twist test
Gun is a XDM 5.25
I have never slugged the barrel but cast coat and size to .356 120 TC and they shoot fine
Any thoughts other than it just doesn't like the long heavy bullets? I should have plenty of vel. and was even going to drop .01 gr. to get it closer to 900 fps
Any help would be appreciated!!!
