Here is overall view of the Armi-Lumar O/U 12ga that has one barrel rifled. Second is another view of the breach. Nice looking gun. Here is picture of the 58cal Minie bullets in 20ga BPI Commander shotcup wads, and some 50cal bullets in 20ga BPI Sport shotcups. Sport wads were too small...

Here is breach picture of that 12ga O/U made by Armi-Lumar It has the bottom barrel rifled right from factory, top barrel smooth, with interchangeble chokes. A real neat gun. Good news, I got few samples of first production run of my 585HE cases from Bertram, to test for strength and measure...

I found pictures of a factory 12ga over under that has bottom barrel rifled, top one smooth with screw in chokes. Will have pics few days. Don't know how heavy barrel is yet. Also will have pictures and test of brass 585HE sent here. They are 585HE case samples from the first big run of...

We hope a company will be making our modeled 12ga sabots soon, this fall, to deliver to reloaders and suppliers.. We also got first part of funds collected for the initial big run for our 585HE long cases being made. Sending in bunch this week, and need more to make run bigger For more info if...

Here is picture of the two ball sabot load, using two 58cal balls in a 12ga Accutip style sabot. Hoping we will have sabot like above for reloading soon, in volumn so we can load and test a bunch of these 58cal bullets and slugs. There are soft cast, hard cast, and the heavier jacketed...

For you folks in Southern Africa, Bertram is getting ready to make the run of my 585HE cases. Would there be a bunch of you interested in a group buy, of the cases right direct from him. If so, no time like now, and he will be able to make more runs later whenever needed as the production...

Sorry, late in posting, bad weather, computer lines zapped again. Some more experimenting with the Accutip sabots, Designed a two ball load using .577" cast lead balls. Bottom ball flattened a little in vise with the flats up and down in sabot. Used a fold crimp, 3.5" once fired REM case in...

With other scoped NEF Ultra 12ga, 24 inch barrel, shot hard cast, 400 gr 58cal Lyman Minie in Accutip sabot at 75 yds. Hit small paper plate 5 for 5. Going 2000fps. Speaking of 585HE above. We have two in falling blocks, 10 bolt guns,5 break actions, and other types. A fun cartridge...

Back after losing time to a lightning fried computer. Test in 3.5" plastic using a few accutip 12ga sabots out of factory loads. The 12ga accutip sabot, hard cast 440gr 58cal minie slug in 36" rifled NEF at 2200, and it went through 12 inches of wood like butter. The hole out showed it was...

Some 12ga sabot progress. Here is pic of our sabot model, two in front, shown with Accutip sabot behind. They are all holding 58cal slugs, showing how tight they fit and conform to the inside of the sabot petals. A decent fit is a help for better accuracy. Hope they get built for us this...

Working more with 58cal lead slugs in 12ga sabot we want to get built. We shot a few for checking penetration, with 440gr slugs at 2200 plus fps. Shooting into popple. In picture the 6x6 on the left penetrated by harder lead alloy slug, with slug showing very little expansion on exit from the...

I think we found good overall sabot design that will be the easiest to get made, easiest to get seals and whatever wads needed... Keeping design simple. It is same simple design as the ones pictured above but with slightly thicker base.It is fairly compact for more room for our slow powder...

Some info we have found out about the operation of discarding sabots. In first picture you see thin white line between the strong powder and the sabot. It is the white fiber cushion wad pressed flat. It is shown on the left in second picture. In the picture of it compressed you see it is...

Here are a couple high speed, stop frame photos, showing how well and even these sabots we want to get made, open up. The petals being thinner with 58 cal bullets or slugs, opens easy. The slots between petals, going into the base aids even opening. We know a couple retailers that are...

The sabots we are working with, take at least 15 different 58cal cast slugs for good fit, with the OD measurement of sabot at .733" with all of them in. There are 5 Dixie Gunworks MZ slugs, 6 slugs from Lyman moulds I know of. Five slugs from Lee moulds.These are mainly muzzleloading slugs and...

Some possibilities with the 12ga sabots we have been looking at. We may have possible leads on companies that can make sabots, that have most of equipment to do so. If they work out ok, the startup cost isn't as high as others who have to set up complete machines. We are working to line up a...

Some more 12ga sabot work. The sabots in first picture are like ones we want to get made for reloading. They have 440gr Dixie Gunworks muzzleloading minie slug. I related earlier that 3 shots with these in heavy rifled barrel NEF got them all in nearly the same hole, at 30 yds. Also 4 shots...

Another 12ga sabot idea, first picture is a 570 gr USS slug, with Powder Cup seal from BPI, locked to USS discarding sabot section. This shortens column so that we can get more of the slower powders in we use, in shorter 2.75" cases. With slower powders, they get to peak pressure a little...

Some more slug setups and ideas. First is USS brand sabot that European cartridge has, without locked base, a discarding 12ga sabot, with .629" brass slug. It is as accurate in rifled barrel as its locked on base counterpart, in smooth barrels. Up to 750 gr brass slug I tested. 3 shots in an...

Here is some more older cartridges and ideas. First is a fellows collection of older brass cases. They look like Berdan primed. Run from 36ga to 12ga, big one on right is flare cartridge. Second is a paper case clad with thin brass nearly to the top. Third is picture of paper case...

Here are some more sabot/slug and loading concepts. First is Alcan 2.75" paper case with Dixie 600gr slug, with the side of the case crimped into the relief/lube groove of the Dixie slug.The groove in the Dixie isn't quite as deep as the groove in the Fosbury slug shown in earlier post, but...

Some more slug and sabot ideas folks are doing. First is a long pointed slug with locked on base, It goes to target with base,can work smoothbore. Second is picture of Hexolit sabot base slug with petals expanded, sure would make bad wound. Third shows a variety of Gualandi slugs you can...

First picture is an RC4 brand slug I see is available down under. It has locked base like Brenekke. And locked on without discarding petals, like US-S. And 2nd picture is a group fired with RC4 slugs by fellow on another forum from a good double 12ga, 2 left and 2 rights at 25yds. This shows...

Here are couple more pictures of longer bullets in sabots, loaded in plastic cases, with the roll crimp down against the sabot. Both are ideas tested by European Cartridge in Greece, who make the US-S slugs. Both longer bullets pictured have the locked on base that their other US-S slugs have...

Here is picture of 4 long cases, top being a Rocky Mtn Cartridge 3.5" turned brass 20ga. Next a RMC 3.5" turned brass 12ga. 3rd down our 3.85" 12ga FH we made from BMG brass. Bottom a RMC 3.85" turned brass 12ga FH case. Next picture shows one of the old ways they locked slugs into paper...

We are always looking for way to shoot 8 and 10s using easy to get components,cheap, without buying loaded rounds for big bucks, if available at all. In 8ga falling block, plastic case got 930gr hollowbase slug to 2300, It is a slug for 10 ga that we expanded base a little to fit tight in 8ga...

Some more slug experimenting and developement. Here are pictures of the full bore Lee Key Slug we had a guy cast. He took Lee Key mold and machined it out to cast a .729" full bore slug. The original Lee mold makes slugs smaller diameter, so that they fit in a 12ga wadcup. Slugs are hard cast...

Some more stuff from the old days--- First is picture sectioned Explora case and slug, showing how they kept weight down so that it could be stepped up in speed in older doubles, that didn't have real heavy barrels. These guns had short section of rifling at the end of the barrel or shallow...

What we are doing in getting more power from shotgun calibers isn't super new or completely novel, most just modernizing and improving older ideas.. In the early days; in my Greener's book he states that gun with a rifled choke section of the barrel, called 12ga paradox shotgun/rifles, with...

Some more gun info. Here is picture of a nice, large diameter action a fellow built, for big bore use.Nice beautiful machine work, He put a 700 short case in it. He called it 700WTF. It would do 12ga, 16ga, 20 ga, etc. Second is the 8 bore we just made on falling block. It is chambered for...

We've worked on the 12ga FH for 6 years. It takes time. Some more gun info about what others around the world are doing with big bores. First is a 4bore Tula pump gun, made in Russia. A few guys in the US have them. They are smoothbore and .938" bore. They used a short 3" long plastic case, and...

Quite a few have wanted doubles in our 12GA long case. Rob is doing one on a big 10ga Zabala double,with Greener crossbolt lock. He is replacing 10ga barrels with heavy 12ga rifled barrels, mono-blocked into the 10ga breaches by threading them into the breach sections. First,2nd,3rd pictures. He...

Now some info on cases and slugs The 50 BMG brass can be made into some real great cartridges, our 12ga FH, shown first, showing cases with rim turned off and threaded; and the 12ga rim pieces to be screwed on, with finished cases shown. And 2nd making my 700HE showing original BMG case...

Accuracy with 12ga FH NEF 3" groups at 50 yds with 600gr full bore and some of reloaded sabot loads, with bad eyes. My 585HE in an Enfield and MRC PH 3-4" at 100yds. That guy built the 8ga bolt from scratch, with steel cylinder and surplus 20mm barrel.I think is is one of the nicest...

I'm visiting here to talk about the 12ga From Hell and other developements it has led to.Nice site you folks have. I'm with a group of experimenters passing on the years of info and pictures to all gun nuts around the net, about 12ga From Hell and other big bores. We have posted some round the...
