St Action Pro 12GA Gauge Shotgun Safety Trainer Cartridge Dummy Shell Rounds with Brass Case, Orange, 10 Pack

These lightweight snap caps help better emulate spent hulls than the typical metal snap caps. Being made on realistic hulls, though, they are not indestructible. The shell stop in a tube-fed shotgun will deform the case head when the snaps rapidly advance in the tube every time you run the pump. A few deformations is fine, but eventually the edge of the rim will deform to the point that it may drag in the tube and cause an issue (especially problematic for a Mossberg shotgun with the spring unable to be relieved from the end cap like a Remington). I don't recommend using these from a full tube regularly. They're good for practicing reloads, but I would not routinely transition to a shooting drill afterward. Having only one in the tube and one in the chamber removes any risk of rim damage; having two in the tube means far less spring pressure is exerted on the one snap that will impact the shell stop. I also recommend numbering the snaps with a Sharpie or paint pen so you can keep track of which get too damaged to use. They have drawbacks, but I still think these are incredibly helpful products, especially with the quantity in which they can be purchased.

Got these so I could instruct my wife in the finer points of 12g Mossberg for home defense. Works well. She was much more confident in handling the weapon knowing she was cycling dummy rounds. I'll do the same for my daughter in a few more years. The shells are high-vis, so easy to spot on the ground in addition to alerting to their dummy status. We've cycled them dozens of times now and they really don't look any worse for the wear. Gonna get some dummy 5.56 so wifey can gain confidence with the AR next.

Perfect for safe dry fire and reloading drills with your 12 ga boom stick

This is the first time I ever used anything like this. I got to say they do what they're supposed to do very well for dry fire practicing

These work great for what they are. Used for practicing loading and unloading a Winchester 1887 shotgun clone, which are famously finicky. They are super lightweight and sometimes hiccup the action, but mostly work fine. They look like they are made on Rio caseheads. I prefer the A-Zoom dummies for their weight, but these work great for the money.

Works great with my firearm.

Without revealing what shotgun I have, if you don't have a modern shotgun (modern as in metallurgically modern) such as an older SxS or over/under then do not dry fire this. These shells are slightly smaller than 2 3/4in shells but in a shotgun that accepts that then it's no big deal. Personally they work great for drills, ejecting, dry firing, but that's because my shotgun doesn't really have super ridiculous tight tolerances and has no issue with them. If you have an older shotgun or a shotgun that one would advise against dry firing (either because the firing pin is brittle or because it's metallugrically inferior to modern equivalents) then only use this product for ejection. If your 12ga firearm is relatively modern then you can feel fairly secure in dry firing these slightly short shells with no problem in the long term. In my experience these are great if you'd like to just run loading drills or mess around with your gun without running safety risks with live shells. A few notes: - slightly shorter than standard 2 3/4in shells - ejects well out of my tested shotguns (nothing rare, nothing older than 30 years) - good for drills - good for messing with shotgun in a safe manner

It's a good product at an affordable price. Semi happy with the purchase. So a little back story. I bought my first shotgun. Mossberg ATI Tactical. Shortly after receiving the gun I made sure to buy some snap caps to practice with. Bought these with 2 day shipping. Arrived on time with no issues! Tested them all out and they all worked...for the first hour...after that they started to have feeding issues. Could potentially just be my gun malfunctioning. But I can't say for sure till I go to the range and fire live ammunition. Pro: -10 dummy rounds for a good price -do their job as dummy rounds -fit and feed in the gun as it should -shipping wasn't an issue at all Con: -stopped functioning after about an hour (could be my gun) -the top of the round has a hole in it for some odd reason causes jammes on some occasions with my Mossberg Over all it was a good product when it worked..but since they don't function with my gun as I need them to they're just over glorified place holders.
