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

Shells functioned well, but were very light. I added two 252 grain .44 magnum bullets into the hollow cavity and hot glued the top. Weight is now right at an average for 12 gauge shot shells and practice is more realistic. Functioning and holding up well, would recommend, just add the weight.

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.

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

Sturdy and good fit

Pros:- Sized accurately for 12 Gauge chambers.- Rubberized primer for firing pin protection when dry firing.- Good dummy rounds to practice shotgun mechanics with.Cons:- The brass portion feels a bit cheap and gets marred really easily.- Just a hair shorter than the 2 3/4" shells.- Way too light to give you good practice with loading.- They jam way too much. I have shot many rounds of skeet inbetween practicing with these rounds and there are no issues cycling the live rounds but when I cycle the dummy rounds, they jam very often.EDIT: I actually filled them with #8 shot and sealed the top with hot glue and it seems to have solved me jam issue and made them heavier for loading practice.Bottom Line:Good set of practice dummy rounds that will let you dry fire and practice loading. If you do some DIY, Jam issues will clear and the weight will feel more natural.

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