12 Caliber jacketed bullets?

[Extreme Accuracy]

Is anyone on here still making 12 caliber jacketed lead core bullets? I’m fighting trying to reduce jackets to 12 caliber and wanted to check here for information rather than reinventing the wheel.

I reduce a lot of jackets down to 14 caliber but reducing jackets down to 12 caliber has been a challenge. I'm hoping someone on here might have already found a way to complete it with better results.

Thanks for any information you might have,

Carl C.

uncle dino in the vendor section makes 12g slugs, mighty fine pieces, almost to nice to send down range

[IllinoisCoyoteHunter]

I think he’s talking 12 cal, not 12 ga. You know, like smaller than 17 and 14 cal lol!! Way too small for my fat fingers lol.

[rancher1913]

well that would defiantly change things

[Extreme Accuracy]

Yeah, sorry I'm looking to see if anyone on here is working with the 12 caliber bullets. .125" bore.

I've been struggling trying to step the 14 caliber jackets down for my 12 caliber rifle. From 17 to 14 has been pretty straight forward but dropping them down for the 12 caliber has been a challenge. I've tried re-annealing the jackets and even reducing in a 2 stage die but have had troubles with jacket punctures and copper stretch.

I thought some of the guys shooting the 12's might have dabbled with this already and found a fix.

Thanks to anyone that might have some help,

Help me understand, who makes these guns and what are they used for?
Thank you.

^^^ Yes - Enquiring minds want to know. Did a quick Google and only 12 Gauge came up. ^^^^

My corbin core mold for making .224 from 22LR as jackets is only 0.185 - still quite a bit larger than OP's desire for made projectiles.

[Extreme Accuracy]

The 12 calibers are custom guns. To my knowledge there are no big production 12 caliber makers. The one I'm looking to swage the jacketed bullets for uses a 22 Hornet case as its parent cartridge. The round is called a 12 Squirrel.

[Bmi48219]

That is a neat cartridge. How about posting a pic or two of the shooting iron it fits. And some info on the maker, cartridge history, etc.

who makes barrels for this caliber?

Is there a trick to getting pictures to upload to this site? I've been trying to upload more pictures of the gun as well but it keeps having errors uploading them.

I have been puzzled by my lack of picture upload capability too. Cursory review of several threads leads me to believe it's a file size issue, and reducing the resolution w/ a photo editor / transfer tool might do the trick, though have not tried (intend to soon). Phones often have high res, high file size, pictures these days. Seems a handy way to get them from phone to site would be to email them to a PC, or even back to yourself, first. That should give the opportunity to reduce file size when sending.

Edit the files to smaller size before you upload them.

I use shrinkpicturesdotcom. As long as you do one at a time, it’s free.

Select, upload, choose size (350 to 600 megapixels[?] is the range I use), select “Best” for quality and download the result to your desktop. Then you can “manage attachments” and put it on this site.

There is a limit to how much space you can use for pictures here, in total. I have to go through and remove old stuff occasionally so I can post new stuff. I don’t use hosting sites, which (I guess) offer infinite space for photos and videos. The prospect of another high tech rabbit hole, with the associated setup drill, doesn’t thrill me much any more.

I guess the ever-increasing resolution of these phone cameras imbues the computer enthusiasts with the illusion of “progress,” but it seems to me I could already project my obsolete Version 5.0 photos on Half Dome from a mile away and still not notice any graininess. And then I have to shrink them anyway for posting. Reminds me of the horsepower race on the “muscle cars” back in the ‘70s. “Where are they now?”

The only site I’ve noticed that gets into subcaliber loading and shooting is Saubierdotcom. They may have a supplier list.

I use a free app called "PicSay" it's one of those services where you can and things to the picture. But I use it on all my forum sites. You go to PicSay and download a picture. It gives you three options fast (low res) normal and high res. I use the fast and it works on all the forums I'm on.

[Kylongrifle32]

Carl I forgot to ask about you 14 calibers. Do you have a source for the 14 caliber barrels? I had a 14 Walker Hornet and a 14-221 Walker in Contender pistol barrels but sold them years ago because of lack of bullets available. The only source I knew of back then was Reeds.
I would love to get another 14 Hornet based caliber. I do have a 17 squirrel Contender pistol now.

Me thinks I would consider swaging .12 bullets using copper wire for this .12 product. I would cut copper wire cores to weight; then heat treat anneal them to make as soft. This thinking based on the movement to mostly copper projectiles for the 5.56 and other rounds used by military and California complaint applications. Doubtful one would break a die as the Copper Core would be extremely small compared to the die body size.

Copper Wire potential for use as a core in this application:

AWG (American Wire Gauge) - 10 = 0.1019"
AWG (American Wire Gauge) - 11 = 0.0907"

Thank you! This is very interesting.

I built the rifle using a Remington 591 action. It has some heavy modifications to the bolt to have the Hornet bolt face and to turn it into centerfire. (It was one of the few very short actions that can handle the high barrel pressures and short cartridges.) My father built the curly maple stock for it. In my opinion the stock makes for a great looking rifle. (Yeah i know about opinions :-) )

I slow rust blued the barrel and action and it seemed to really go well together with the stock to me.

Beauty is in the eye of the beholder though….

Mike, I bet I know who bought your 14 caliber barrels. Did you happen to sell them as a packaged deal? We picked up a new customer looking for 14 caliber bullets awhile back that sure fits the description of your old barrels. I have him beta testing a new light weight bullet design for us now.

I'm currently down to my last four 14 caliber blanks. If I can get another batch of them made I think I'm going to fire the old 14 caliber website back up and start selling online again. It was getting to be such a fight with anti gun credit card processing companies that we went back to just selling direct to our old customers.

Wish you the best of luck on your upcoming shoots,

After I got my 17 Ackley Hornet sorted, I really thought I wanted a 14 caliber something or other. (In what I hope is an un-insulting way of saying this) I am glad I didn't, because I just don't have the time/money/skill set for the bullet manufacturing. They really are interesting though, and for years I wondered if there were 12s. Now I know...

In a serious vein: what are the BCs, and how is wind drift in 10-15 at 200?

BTW, FWIW: I think the maple stock looks nice.
If I can figure out how to place an avatar pic, maybe there will be another maple stock that looks nice to the owner pictured on the site...

[IllinoisCoyoteHunter]

That’s a beauty!! Very nice Carl!

[Kylongrifle32]

I sold them separate but Cody bought both of them. He also bought another interesting barrel I had. Fred at Bullberry made a 17 Thorpe magnum he called it for a friend of his. It was a 17 cal barrel that fired . 177 pellets inserted into the chamber and fired by a 209 shotgun primer.

Good luck with your 14 cal swagging project.

I'm also on the Saubiers forum as Kylongrifle over there. Keep me in mind if you get some barrels back in stock.

TurnipeaterDown, not a bit insulting and brought a good chuckle out of me because I've said the same thing to myself a hundred times :-)

On your question about the wind drift. There are 2 way to fight wind drift. Heavier projectiles or get the bullet there faster. People are often surprised at the lack of wind drift from very high speed rounds. Since the bullet is only impacted by the wind for mere fractions of a second it isn't effected as much as a slower bullet. If you push past 200 yards with the light weight bullets they are slowing down very rapidly and the wind really starts to effect them from there on out.

I would regularly shoot the 14 caliber 17.5 grain bullets on prairie dog shoots out to 300 yards. The wind drift was about the same as the 222 and 223 at the same distances. From 200 yards and under I very rarely dopped much for the wind. On the 8.5 grain to 12.5 grain bullets out to 150 yards I never dope for the wind. You see the bullet blow up the target in the scope before you even know the gun went off. With almost zero recoil you watch it all happen in the scope at those ranges.

Bullet BC's very depending on the bullet tip design. The 17.5 grains have a BC in the .145 range. The 10.5 grain MEFS drop down closer to .135 to .130 range depending on point forming die settings.

Oh and just so you know the guy that built my 12 caliber barrel also made a 10 caliber barrel as well. :-)

The 17 Ackley hornet you have is a very fun shooting round as well.

Wish you the best of luck on your upcoming shoots,

Kylongrifle, now that sounds like a fun gun too! I'll keep you posted on the next batch of 14 barrels. I'm leaning hard on 1 in 7 twist rate as I own and have sold so many of them. They have all done very well for me but the last lot of 1 in 9 twist barrels and the lighter bullets has flared my interest in the over bore 14's and the very light weight bullets too.

I'll keep you posted on results for both in hopes it helps you with whatever build you decide to go with.

I have a 14 TCM Extreme cartridge build that I'm very interested to get more results from. I spent a lot of time designing the reamer so I sure hope it isn't a flop....

Stay on target,

Carl,
Thanks for the info on the 14. Neat.

I did take the 17AH on a couple week long PD shoots, it was very good for me to 200 yd w/ 18 gr Berger MEF @ 3800, and to 250 yd w/ the 20 HP Berger @ 3650. 20" Carbine TC Contender, old 6x Weaver K6 dot & hair scope that came of granddad's 30-06 deer rifle when I inherited it.

I did also take the std 22-250 on PD shoot trips, and a big 6 mm off a 280 Rem Imp case. I did most shooting w/ 22-250, but that 6 left a lasting impression when it got used on one unfortunate PD at about 70 yds when a 55 Nosler started at 4350 fps connected.

When the barrel fried on the 250, I put a 1:9 on it and I use 68 & 75 Hornady HPBTs now at 3250.
Never got back to the PDs w/ a 6-250 IMP I built (1:12), but it does shoot well.

Thanks for the interesting thread and pictures.
