Making your own 1 3/4 inch 12 Gauge mini shells.

Recommended Posts

Anyone make their own 12 gauge mini shotgun shells?

Aguila manufactures them, that I know.

They've been around for about 2 years now.

I've made my own 2 3/4 to 3 inch 12 gauge shells in various loads.

This is a project I'd like to do & been in my list to do for over a year now.

The loads I want to make are # 4 , BB's & 7/8 ounce slug.

So anyone care to share a recipe for a mini 12 gauge shell load you've made?

Now this is personal opinion and not meant for information for any persons dead or alive / living or dead.


Danger will Robison warning warning BEEP BEEP eeOOOOOOO eeeOOOO holy crap don't do it.


now that being said----


Sans the wad,  use a gas seal  everything else would be the same as everything between the powder and shot is a spacer 


If you use something that you need to protect the bore from, then a gas seal combo cup would be the way to go.


cut it for length and then overshot card and roll crimp I would not fold crimp period IMO.


Now the real problem in a standard chamber these can roll over and end  standing or reversed now a 2 inch shell makes a lot more


sense in functionality.


to a point a shorter shell makes for more in the mag tube But they have to function at 100% reliability 


Agila shells have been around many years and it is not a new concept I think it is English shells are 2 inch for break open guns.


As long as the data is forX  Hull {type}  X powder X amount of shot and no variation, then what changes ?


All of this is an exercise in mental agility only an assumption and not for real world use.

Just finished making one of these MINI shells an hour ago.

I've cut the hull down to about a 2 inch length overall.

Used a white-clear ward that I normally use for 2 3/4 inch hull.

Powder charge 800X  15 grains & 1 ounce # 4 shot.

Cardboard caped & rolled crimped.

Will be shot from a single barrel brake top shotgun.


WARNNING, I do not condone using or making any of these mini shot shells, do to the info stated above.

Making these shells will be the onus of your own doing & I will not be held responsible in any part.

I think 2 inches is a good length overall it would give you one more in the tube  a very slight edge, but as far as ballistically


Should not be any difference in performance all things being equal.


I think the best load would ne 7/8th to 1 ounce of course you have to pattern the gun I think this is a good candidate for


#1 to 1 1/2  buck .300 to .308 diameter lead buck stacks good and has enough to get the job done,


I love the BB's perfect size for birds clean knock down or miss the smaller shot is not humane not that I am a purist or a fanatic


But as I can when I can I do not like to wound and I don't like picking sand shot out of my food either.


A 7/8ths ounce slug seems a fine thing at about 1100 to1200 FPS I don't need it to kill on both ends.


Well, I have seen some listed data on 2 inch have to look for it I imagine BPI load manuals will have some listed.


I do not care for loading hulls past 3 times for all I have seen and read diminishing returns and with components,


costing so much I would like to get data results from my loads.


I am getting some brass magtech shells I have a roll crimp die that will just roll the edge enough to hold the overshot card


without leaking a bit of Elmers glue and the shell should stay dry and tight.


One reason I have not done it yet is the internal dimensions require oversize seal wads and I do not need more stuff


but I may get a box to keep in storage I have punches and could make my own wads if needed but that is a pain


I have plenty of felt, cork and chloroplast to hack out wads from if push came to shove balsa or dry bark would make do


Just don't use them in a dry season Ol' Smokey bear would not like that, and people need to THINK it is rare but it can happen


When using alternative materials for wads and cards.

    • This is a great inspiring article. I am pretty much pleased with your good work. You put really very helpful information.
    • here is the survival coupons codes to get a amazing material of survival struggling 
    • Hey all, This is sort of cool (okay really cool) and maybe some of you have heard about it because it's been plastered over FOX and mentioned by POTUS as well as other conservative-leaning news people (Huckabee, Diamond/Silk, Candace Owens, Mark Levin, etc..) and politicians. #walkaway is a movement based mostly on social media. Started last year, by Brandon Straka (pronounced Strawk - like "straw" with a "k"). He's a former 2016 HRC-voting hair stylist, from NE, now in NYC, homosexual, liberal who began to question the MSM and what he was hearing. He got really frustrated as he began to do his own research. Anyway, after having his own awakening to the lies of MSM he had been following, he began an online testimonial campaign in which former liberals can post their #walkaway stories, written or video. Many are now on the "Trump Train." Many have simply left the Left. Still, others have always been non-Left and are members in support. The amazing thing is how many different people from all walks of life are beginning to wake up. Lots are not conservative on all issues, but all have a love for the USA and dislike the demonization of open political and social thinkers and speakers. This group gives solace to people scared to voice their conservative opinions or views for fear of negative professional or personal responses. It now has budding smaller groups in all 50 states and an online discussion group where people discuss current topics or issues (WITH no vitriol, gasp).  Here's the original video from Brandon. This man, Brandon has a unique, stylish, well-articulated voice to help move people "in hiding" out into the open and not be silenced. Pretty much any video Brandon does is great. Here is the Facebook page: As I see fights erupt online, I simply leave #walkaway in the comments. Brandon has a goal of 1 million members! The liberal media has called this campaign "Russian Bots" and "paid actors." It's not!!!        
    • thanks to all who  have served or are serving our great country....243 years in the making....   Trump did a good job today thanking each branch of our military and a long time coming salute to the coast guard too....
    • I can imagine food prices going up this Fall or Winter. Corn is used for live stock feed, & us humans consume a lot of corn based products, as well as corn based biofuel. I’ve been keeping a watchful eye on the mid-west of America, which is flooded by water. Where corn  & other crops are normally grown there. Farmers are quite worried about this years growing season. Time to stock up on extra food if you can, if you haven’t already. Stack it high, stack it deep. Store the foods that you normally eat. What ever the  amount of food you’ve stored,  try to double it if possible. Better extra safe, than sorry.
