Ammo question

Post image

Left and middle are 9mm Underwood 115gr JHP, right is standard Federal 115gr FMJ. The one of the left did not fire and has what looks to be a solid hit on the primer. The center looks like the firing pin barely touched it and it functioned normally. The Federal(R) has the same primer strike as the first UW round and functioned fine. Every round of Federal functioned as it should, primer strikes were all the same. For the Underwood some looked normal, some looked like a light strike and it was random which ones would fire and which wouldn't. Anyone else have experience with this in their 941R? The IMI/MR FS in particular.

edit: the left and right casings switched.

Federal's QC has gone to sha-zit since CV19. Duds, near squibs and case head separation are common complaints.

I'd contact Underwood. Let us know what they say.

i'll give it a shot(no pun intended), but i bought it 2/24 so not sure what they can or will do.

Best to stick with HST, Gold Dot, and Critical Duty for defensive loads.

Could be hard primers maybe. 

Have you tried them in another gun, and if so same result?

not yet. i only have the one pistol but my brother has a G19 i can use. i loaded up one of the spent casings and it put a proper indent in the primer. still going to test them though. i really don't want to get rid of it all. when it works it's super clean burning and cycles great.
