I'm having some troubles with mine suddenly. I've put 200 or so through it previously with no complaints, but last week I took it out to shoot trap and was getting a lot of light primer hits. Like 1 out of 3 would fail to fire. The shells would usually fire when I ejected, then re-chambered them. Sometimes had to do it more than once. I've used this ammo before without issue, but switched to a box of federal with the same poor results. Frustrated, I went home.
After googling around for ideas, it was suggested that the bolt might not be going fully into battery which would result in a light hit. When I slowly close the bolt by hand, I notice that it hangs up and is difficult to get it to rotate and lock. If I let it slam forward normally, it seems to close and lock ok. I disassembled and cleaned the bolt, greased the bolt retaining/camming pin and lubed everything else up. It still hangs up a bit - but only if I slowly close the bolt by hand. I don't have another Stoeger around to compare it to to know if this is normal.
I'd welcome any suggestions on what might have been occuring. The gun has an MOA bolt handle that's been working fine for some time now. The only thing that happened to it before it started malfing was a cleaning.
Edit: here's a (poor) video to illustrate
