## Description

Official product of ST Action Pro, brand new. Developed for military and law enforcement use - brass case with ABS plastic insert makes the round highly visible. Popular with many departments and agencies for use in immediate action training for just that reason. Completely inert dummy training round. Excellent for classroom training, loading/reloading drills, gun handling drills, malfunction drills and diagnosing shooting problems. Each round uses a solid brass case so there is no chance of rim breakage. Made by ST action pro.

Review: Shorter than 2 3/4 in., do not use in older shotguns - 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
Review: Nice trainers - 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.

## Questions & Answers

**Q: I have 2 shotguns that i want to train on. one takes only a 2 3/4" shell and the other only a 3". will these work in both shotguns? ty for replies**
A: 2-3/4" shells when crimped measure to about 2-1/4". If your shotgun can take 3" shells it can use the 2-3/4" shells with no issues.

**Q: Can these be used for dry fire?  Isn't drt fire part of a drill?**
A: Yes, this is the reason why i bought it. This is also good for practice how to load, reload and dry fire.

**Q: Do they cycle and feed well? How do they hold up after time? I plan to put two in my side by side to relieve stress on the springs from firing pins,**
A: They cycle and feed great! As for holding up over time, I haven't had them that long, but the brass part of the shell gets most of the wear, and since it is brass, I imagine it will hold up for quite a long time. It's a good well-made product in my opinion.

**Q: I suppose these are not good for dry firing since the pin will not contact anything?**
A: There is a chunk of plastic for the firing pin to strike.

### ⭐⭐⭐⭐⭐ Very helpful tools, but understand that they are consumable
*by T***O on October 13, 2021*

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.
