Ammunition failure in M305

[Northern Amateur]

You should be able to get the stuck case out with the chamber brush?

Ditto. Worked like a charm for me. Place a .30 cal brush inside the case and pull it out.

I have had several case head failures with this ammo as well. When one of them let go it blew the floorplate off the mag and dumped the remaining ammo with the mag spring.I bought the utg broken shell extractor, but havent had to use it yet. I think its just the casings, not a headspace issue, i fired tons of norc ammo after and it never missed a beat.
