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

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.

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

I keep in the mag to keep the spring under tension and cycling action

I purchased these as training aids for firearms classes I teach. These are some of the best dummy rounds I have used for shotguns. These cycle the best out of all the ones I use. With that being said they are no where near as reliable as real shells as far as cycling them through a firearm. These are perfect for teaching new shooters how to properly load and unload shotguns while maintaining safety. These will jam every now and then but not as bad as any other dummy rounds I've tried. These typically last me about a year before the wear and tear starts to become problematic.Perfect for practicing those John Wick quad loads when nobody is watching.

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.

They work for their purpose. They are a little light at 13 grams and non standard length at 2.2 inches.

These are great for practice, training, etc. Cycle like live rounds.

Most of us use training dummy shells for, ahem, training. And the first element of training is to recreate an accurate duplication of the real world experience. These dummy rounds fail at this, completely.There are two important things when you're practicing shotgun skills, which in large part revolve around tactical reloading. You want shotshell dummies that are the same size, and of close to the same weight. Only if you have both these factors, can you then realistically practice, develop muscle memory, and become skilled at handling your shotgun.These dummies are way too light, and also way too short. At best, they are maybe 2 1/4 inches long. Most of us, particularly in tactical applications, will be using at least 2 3/4 inch shotshells, maybe longer, all the way up to 3 1/2 inches.There's no way you can develop micro-motor reloading skills with training dummy shells that are so ridiculously shorter than the ones you'd use in a real situation.So, a total fail. Sure, they are low cost, but don't waste your money on something that will teach you bad rather than good habits. As always, I marvel at the abundance of short five star reviews......
