I recently picked up a Glock 20. I am working on reloads I have some175 gr Barrys plated and poly coated hardcast. I am using VIHT N 340 powder. Test rounds run at 7grains:
Barrys = 1047 and 1072 fps
Cast = 1105 and 1109
Pressure signs all good so far
Hornady says 7.5 max on 180 grain bullets I would like to get 1250 fps. Being that the bullets are 5 gr lighter than book how far past 7.5 max could I safely go?
