The A-ZOOM & Volein 12 Gauge Snap Cap, Dry Fire Practice Shells all jam my Vang Comp Rem 870 tactical shotgun. Anyone else experienced this? Live rounds are no problem, just the dummy rounds I bought for safe, in-home reloading drills. Arrggg...
Rather than snap caps, get some action proving dummies from Brownells. You can’t dry fire them, but they feel and weigh much closer to real shot shells than machined aluminum snap caps.
I have experienced this using 1897 and 1887 Winchesters.
