10 Gauge or... 8 Gauge ? |
|
|
8 ga. industrial slag / vat cleaner round with the belt turned down.
Olin mfg. |

It is the 8GA From Hell, a real cartridge. 4.3 inch long
brass case. 8 ga shorter plastic case, plan on in same chamber. The brass kiln gun case isn't as long as mine. Where do you find the rare 8 ga brass kiln gun cases. Looking now for guns or actions and barrels. I make it from 20mm Suzy brass(20mm Hispano Suiza), by putting on a 8ga size rim and reshaping like we did 12GA FH....Ed |

To get an 8 ga. Foster style slug w/ HP that will ensure obturation, you will most likely need to commission a custom mold and cast your own using a relatively soft alloy. The good news is it should only be a couple hundred bucks, more for multi-cavity. The bad news is that you have to cast your own. You may also need a custom sizing die, depending on how close you can hold tolerances with the mold, and the hardness of the alloy. I'd call Olin on a Friday afternoon and see if you can get a tech on the line who like to talk shop. |

Use the black &/ or gold colored Brenneke slugs in any rifled barrels. Otherwise you gonna end up with some SERIOUS leading. And the slug will just strip past the lands once you get much past 1700 fps.
|
|
The first barrel shown on 87 is smoothbore so i can test different
softer slugs that are advertized for smooth. I fired Brenekke KO soft slug in rifled NEF at 2000 fps.and there was no leading. That locked on wad seems to cut leading. Others say the same. I bought the slugs rounds for 55 gents each and took slugs out and reloaded with our experimental loads. In the long smooth barrel, I think in 3" plastic 2400 or more.Ed |
|
Got an 8ga barrel blank being made now,
will be here end of the week.Found this info on plastic 8ga kiln gun loads, they load a frangible 710gr slug at 2300- for 8300ft lbs, load 1275gr hard slug to 1700, 8100 ft lbs. We will outdo those easy with our non-shotgun powder loads, in a heavy barrel.Ed |
|
Tested 35" smooth barrel in 1887. Got couple
1 oz foster slugs over 2400, with 110gr of 4227. 3" plastic case, regular primers. This is a heavy barrel for that type of load, don't do this in your 12ga skinny barrels. The 28GA FH cases on the way.Chambering bolt gun for it now..Ed |
|
In the 87 long smooth barrel got
1 oz Brenneke to 2400 with 110gr of 4227, You could use 4759 and VV110 also at lesser amounts. Barrel is cylinder bore size. Brenneke slugs need no wads as the locked on wad works good.Ed |
|
In the long barrel 87 got 600 grain
Dixie over 2000, got a Buckhammer slug I took out of factory load over 1900. Buckhammer and locked on wad is 630 gr. Tested in 3" plastic cases. The firing pin on the 87 didn't protude out like I like them to as it comes from factory, so I removed .015 from the hammer stop. It fires big and small primers perfect.Ed |

10GA FH..a NEF 10ga, medium to heavy wt smooth barrel.
28" long, gun weighted to 14lbs. factory FED 765gr loads are 1300 fps. 200 gr of first powder tested is 7383 surplus and the regular shotgun primers got 765 gr to 1600, for 4300 ft lbs. Case won't hold anymore 7383. We will test 4227 with the same slug , and saboted slug of some design. The 765 gr Fed slug is hollowbase for smooth bores. Roll crimped with crimper in drill press. Case expansion with 7383 very little(.006") like the factory loads. 3.5" plastic cases.Ed |
|
10GA FH info.Fed factory hollowbase slug is .025" smaller than
10ga bore. I bumped it up to the .775" size, by expanding hollow base. With 7383 that gave another 150 fps.Fast starting shotgun powders expand base better than much slower 7383. The Federal factory load has 120gr of wads/seals about 1.4" long. Better to replace with much more slower powder, getting better velocity, still at low shotgun pressures.Ed |

First two cases are ours we had made by putting rims on bmg
brass, The right ones a santa sent me and appear to be drawn, high strength case that are same dimensions. Are they worth rounding up, seeing as how the guy who made our first bunch just closed and retired. .......Ed |

Any word on use of Saiga 12's? I'm thinking about loading up some brass from Rocky Mountain Cartridge
I'm thinking 3'' shells with 600gn Slugs. I need advice on powder and a way to crimp the shell. Also a powder that works best in an 18'' barrel. I'm also getting a swage press in the next 3 months so I may be making slugs soon. |
|
SOC- A Saiga will have to be future project, got
10 other projects ahead. As for loads for 3" RMC brass, with 600 gr slugs, start at 90 gr of 4227. For crimping I use a swage type crimp to force brass against slug as opposed to rolling the case mouth over the slug or into groove-- cases are too thick to roll and last very long doing it. Ed |
|
In 10GA NEF 110gr 4227 got 765gr slug
to 1800, ejected ok. If it was a really heavy barrel it could do more.Using the 7383 surplus at 150 gr, don't even have to resize to fire 3 times. The 28GA FH done and testing in next couple weeks.Ed |

Here is picture and info on Royal
Arms' site for hopped up 12ga loads, used in little cannons for bomb work. Anyone got any of these fired that I could inspect to see how they are built.ED http://www.royalarms.com/EOD/ammo/canonammo.gif |

28GA FH research. Guy on forums suggested using 54cal
rifled barrels for 28ga as they are easy to get. I looked into it and did some testing. It is ok as long as you keep bullet about 400gr as most 54cal barrels are not super alloy. You got to use the thick heavy ones also, being stronger. And everyone with 28ga wants slugs and there is no slug loads from factory, and to reload the heavier bullets we shouldn't use these barrels or regular 28ga barrels with 600-700 gr slugs. But there are couple dozen 54cal bullets out there stocked all over the gunstore shelves, in weights from 300 to 450 gr. There are heavier but for 28GA FH on deer 400gr is great. I tested the 405 gr copper plated Powerbelt brand, with velocities from 2300 to 2800 plus fps. That's 6500 ft lbs. The 54cal slugs load tight in the RMC 3.25" 28ga case fine by sizing top a little tighter. Bullet obturates to fit .550 bore as bullet is hitting target straight. A lot of 54cal barrels go from 530 to 560. 54cal slugs range from .534 to .560" There are different sizes of 28ga barrels and chokes, so some where there is lighter 54cal slug that fits.. And with light slugs the pressure limits with the MRC brass match top muzzle loading pressures, so these barrels will work. And great thing is the 54cal barrel guys ain't allergic to making long barrels. I've shot one MRC case 15 times and still going strong...Ed |

28GA FH testing. 405 gr in 2.75" plastic case
got 1400. Tested the Great Plains 54cal lubed slug, runs from 2200 to 2700. It is by Hornady and its front band actually measures .550" and hollowbase. They hit target straight. Got a bunch of 415gr hollowbase coming that are 548" from Dixie Gunworks. Only 26 cents each. All will work in plastic or long brass case. I found another .550 bbl and coming, and it will go on a Mossberg 12ga bolt action for the second 28GA FH to test.. Ed |

Tested the 415 gr hollowbase slugs in 28GA FH long
brass case. These are ones that Dixie Gunworks sell that they call their Sharps .548" slug. They all run about .008 bigger than that so they make perfect tight fit for .550" barrel, and I used a good lube on them in the grooves. Same speeds as above for GPs. They are a little harder alloy slug than the Powerbelts or Great Plains The 28ga shellholder for our Lee, Lyman, Rcbs presses , we use, is from RCBS for regular metallic press rams. For 28ga dies Hollywood made some for metallic presses.Also for sizing for bottom 2/3 of the brass case you can cut top off of the 500J die.The slower powder loads don't even have to have the bottom half sized, which is great for a turned case. If we had drawn brass cases we could get 11,000 ft lbs, in the Enfield, which we don't really need for deer. 4-6000 ft lbs ok/deer ..Ed __________________ |

I get asked about hopping up 410s with brass cases.
A good drawn case is 9.3 x 74R. It'll work in 3" 410 chambers or shortened for shorter chambers. I am not doing any, just passing on info.Ed |

If there isn't a F/A belt fed version, I'll stick to plinking with Barretts. |
|
Well Barretts, McBros, etc can be rebarreled to my
700HE. Got a guy doing a BMG bolt upper into one. 22,000 ft lbs, and that kinda energy don't need real fast firing, real serious plinking.Ed |

The hollow pointed slug above can have a
light plastic/rubber nose for streamlining for better BC, for 2-300 yard shooting. In the 87 Win Levergun, smooth barrel, long barrel, using brass RMC 3" cases, 1 oz Brenneke KO slug to 2700 with 4227 powder. Shotgun primer. I will be getting some 3.5" RMC brass that he will put a special longer corner radius in, to allow faster loads with less case expansion and easier resizing. Should get same slug to 3000 and resize easier also. With shotgun primer able to use 4227, and you WON"T have to rework hammer or firing pin to do big primers.ED |

I just noticed this thread and had to read the whole thing.
All I can say is, "FUCK!!11!!" |

Is there anyone that I can buy some FH rounds from that are loaded 2.75 OAL IE Standard 3'' is 2 3/4in OAL and 3'' after being fired. Hot plastic hull would be good. Hot brass hull would be great. And a hot brass hull crimped around a 600-750gn slug "Huge rimmed pistol/rifle round" would be SIC! Looking to feed them in my Saiga-12 after the rest of my parts come in from Dinzag O I'm in NC if the potential seller would like to do a little face to face. |

I'm not legal to sell loaded ammo. To get hairy loaded
slugs of that weight you can contact Dixie Slugs. They load 3" cases that are about 2.7" loaded. Another one is the hot loaded REM factory Buckhammer slugs.They are about 630 gr. When you get something post on here how it works.Ed |
