So the G40 on the bottom took a nice deer last year. I used Federal 190 grain JHP duty ammo that was probably 20+ years old. With the SRO I can shoot a group at 50 that my hand can cover, couple of inches at 25 off a modified rest simulating field conditions. On the off season I ordered some Underwood 200 grain flat nose black cherry hard cast to hunt with this year.
I went out today, shot ten rounds of the 190 grain at 25 to confirm zero and then went back to 50. I shot from a solid bench off a solid rest. The first five rounds of Underwood were all over the place, I mean 16 inch spread. Shot five more, same thing. Loaded five rounds of the old JHP, and sub 4 inch group, dead in the diamond.
What gives? I’ve never read anything bad about Underwood and everything says hard cast shoot fine from a Glock. Bad batch? Next week im going to take the M&P 10 with the RMR, which I just zeroed, and try the ammo through it. The experience was disheartening.
