12 gauge military look display shells

A nice set of 4 12 gauge MILITARY LOOK display hulls. These look a bit more ‘military issue’ with the OD green plastic hulls. All have a neat roll crimp over a neutral colored overshot card under a clear protective disc. “High brass”  2 3/4”  hulls made with 1 1/8 ounce of shot. Blaze orange disc visible in primer pocket. Maybe perfect for a shotgun display.

Completely inert.

Here is another great visual aid for the classroom or just a really cool display set. This is a set of 4 different 2 3/4” 12 gauge shotgun shells, each with a different load. They include #8 bird shot, BBB load, 00 Buck load and a very nice 12 gauge slug. The best part is the shells are translucent and a transparent shot card is used under a roll crimp! These look great and are the best and easiest way to describe and show what goes into the makeup of different loads. The entire shell is INERT but looks like the real deal down to the fake powder (actually coffee grinds), a cork buffer, a wad that has had 2 of the ‘petals’ removed to better see the load, and a transparent shot card.  

Very cool!

I had requests from law enforcement to make up a 12 gauge 2 ¾ inch training round that was blaze orange, full weight, high brass and of course as inexpensive as my other shot shell options. With the blaze orange hulls, orange overshot disc and orange discs in the primer recess, these are perfect for in firearm training. Built with new hulls, 1 1/8 ounce of #8 shot and a military style roll crimp. Completely inert.

These full weight 12 gauge training rounds are great for all levels of shotgun training. With new clear hulls, 1 1/8 of #8 shot and a bunch of 'glow-in-the-dark' plastic BB's these are perfect for in firearm training. These help the user learn the all needed muscle memory in low or no light so they will be able to load and clear malfunctions in any light when it really counts.  These will glow long enough for a round or two of total darkness or low light loading, unloading drills. When they get dim, hit them with your flashlight for a few seconds and your ready to go again. They even glow in the primer recess so if they hit the ground (all full weight shotshells are top heavy) you can see them sticking up in the sand or grass. Of course they can be used to train in any type of light they just have the added benefit of the glow! COMPLETELY INERT!! Features a military style roll crimp and clear overshot disc. Sold in sets of 4.

These are the MINI shotgun shells that you may have seen. Of course completely inert they measure 1 3/4” long and have about 7/8 of an ounce of #8 shot.

Built with new semi transparent hulls and a clear overshot disc . Blaze orange disc visible at shell base.

I couldn’t wait to see if these would cycle in my shotgun (they do!) And man does a 10 round extension hold a lot of these! But they may not cycle in all semi auto or pump guns. Google ‘mini shells’ and your gun to see what others have found. Still, a nice inert model!!

All of the 12 Gauge shotshells I offer are made using only top grade brand new components. They are also made to be as close to the weight of a “live” shell as possible. The user can feel confident that if he or she is training with my inert shells the proper balance and weight (that is so important to muscle memory development) of these shells are approximated as much as possible. I have shells that are perfect for many different training and teaching environments as well as varying levels of training proficiency.

All shot shells are made full weight realistic!

These are really cool! I am calling them my DISCO training shells because of the red shimmery paper lining the inside of the shells. They don’t glow like a disco ball but they do look distinctive. They have the same stats as the above item. 2 3/8 inches long, low brass, 1 oz of lead and a neat roll crimp. Your training rounds will certainly stand out! Great for 3 gun training.

The finished size is 2 3/8” so they are the same length as most common 12 gauge shells. Like the “Disco” shells below these do stand out!

I am taking a long needed break from making my dummy bullets and should return with a modified product lineup and new website by November 1st. In the meantime I will not be taking any orders. I need to work on a bunch of projects and maybe even take the first in a decade little vacation! Thank you to everyone for the continued interest in Dummybullet.com! I shall return.
