trouble
We just had a problem similar to this, we were trying to run a rifle class in our indoor range and we used Frangible Ammo (Sorry I do not know the maker). After NUMERous malfunctions, where rounds would not feed and it seemed like they were crashing into the receiver and not feeding. By the way this did not happen with Federal XM193 in the same gns on the same day in our single lane rifle trap. When we compared the case length of the crappy non-feeding frangible ammo to the XM193 I noticed the XM193 cases were longer. I do not know how much longer, but they were longer at least an 1/8".
TRY this. Compare your above ammo to a known QUALITY not reloaded ammo.
If not you did not waste any time or $.
Take Robb up on his offer.
I hope I added something.
