Hi, friends.
I've got a new Beretta 1301. It has a little over 200 rounds through it.
This last weekend at a comp I was performing a slug changeover and unknowingly induced a malfunction.
During the changeover, I must've ridden the bolt carrier group forward and gotten it stuck, because when I pulled the trigger, all I got was a "clunk." I thought it was a bad primer, only to find that the primer was never struck at all.
Essentially, the BCG gets stuck just before the bolt itself rotates into battery. It actually takes a pretty decent "tap" on the charging handle to get the BCG to overcome the "hump" it gets stuck up on. Once I get it past this hangup point, the bolt rotates and the BCG moves forward into battery.
I've been able to reproduce this at home with and without dummy rounds (pics attached).
I should note that during normal firing from the magazine this isn't an issue. If the BCG has enough inertia, it blows right past the hangup point.
I'm wondering if it has to do something with the cam pin getting stuck in the cam raceway. I dunno. Out of Battery (sticking point)
In Battery (after a good tap on the charging handle)
