Shotgun shell snap caps
Am I wrong to think that snap caps should cycle properly in the A300? Load the tube, push the carrier stop button (which fed a shell onto the lifter), then charge the bolt. Everything is hunky dory.

Charge it again. Shell in chamber doesn't fully eject, it hangs up in the port. Clear that, let bolt feed shell on lifter into the chamber...no shell from the magazine moves back onto the lifter. I have to press the carrier stop button again.

Am I missing something or do you get what you pay for with snap caps (I got some generic ones, not A-Zooms)?

I've had trouble with snap caps in other shotguns, but I thought it was either something I'd done wrong or cheap snap caps. (I don't remember the brand.)

I'll look again after work. I'm curious to see what we learn on this one.

If they are the plastic bodied ones without weight/lead in the front I wouldn't be upset if they didn't cycle properly. Mine don't always do what they're supposed to.

I picked up a box of the Jerry Miculek-branded inert/dummy rounds from Fiocchi for this reason. They're not snap caps as they don't have any accommodation for the firing pin, but they're shotshells with a proper crimp and a load of shot. I think a box of 10 dummies cost as much as a pair of the nicely weighted snap caps.

Sure enough, no weights in mine.

Mine either. Would the lack of weight account for them not going from magazine to lifter to chamber properly?

I just grabbed a box from Miculek.com, thanks!
