Here is picture of a falling block a guy on Weaponsforum has picked up to finish. The fellow who started building it laid it aside for awhile and the new guy is going to finish in BMG. It has 50cal bbl on it. Looks easily big enough for 12ga,10ga,8ga, my 700s. The lever on left is cocking mechanism, The tube in back is a firing striker and spring and it hits the hammer block you see in the back of the breach block, which hits firing pin ahead of it in breach. It is the the only one like it. They've put a lot of work into it, especially the hammer block striker setup.Ed |

In related big bore work we got a Montana Rifle Co, PH action setup in my 700H 3.25" case. Fired test load of 825gr at 3000 fps. This was just one test load. Normal max loads are 825gr at 2850 and 1000gr at 2700.Hunting loads 24-2500, First PH fired outside the factory.It is in first picture. PH will work for any big case and my 585HE.And if anyone looking at big actions for 12ga FH, here is picture of MRC PH with a 3.5" 12ga case partly into action. The PH cam be used for 12ga with action and rails opened like I did my 700H in Enfield. And a little changing on the bolt face and extractor In 12 ga it still would have 60% of front lugs contacting and you'd add bearing lug surface to bolt handle base so it would handle same pressures as Savage 210. And 3.5" with average length 12ga slug would feed from the magazine. Our longer case would work with port opened and some mag work. Ed ![]() |

Got single stack mag figured out for 12GA FH and my 700H 3.25 in PH. I fit a bolt action 12ga box mag and its follower and spring inside the PH mag box. Easy to fit in metal box, and permanently mounted to metal and floorplate. Holds 2 down. That way feed lips already a working design. And opened back of 12ga box for longer case like I did with my 700 in Savage 210. Also work for anyone doing a PH in 12ga FH if they aren't loaded too long or with 3.5" RMC cases. Using most cast 12ga bullets like Dixies, the overall length with 3.5 brass is 3.9" and fits 4.05" box ok. Here is picture PH from bottom showing its big size.You can see in pic there still is room to make box longer yet. And the feed port can be longer.Montana Rifle has great action here with lots off room and strength.Ed |

I got barrel on the 4ga/bore falling block gun. Barrel 32" long, 1.87" breech, gun is 27 lbs. Notice breech block is down and huge hole in barrel. Maybe shoulder cannon is the right term for it. It is all inleted into thumbhole laminated Vulcan 50 cal stock, of which I need more, if anyone knows where there are any. 4 bore cases shown, and I'll use a big ammomaster press for them..Ed |

Here is a picture of the front end of the 4bore, showing a 2000gr slug protuding out. Simulating stop action photo work, as if anyone wwould be brave enough to put a camera out in front of it when it fired. Will have it firing by fall. I plan on using hollowbase lead slugs of about 1600gr, as it is a smoothbore. Ed |

I got 3" chambered 12ga set up to test loads with RE-17. Many guys want loads for 3" chambered slug barrels as they come from the factory., So I put extra 24" Savage barrel I had on a Mauser GEHA bolt action. Rifled Savage barrel is modern steel with .93" muzzle diameter. Original barrel on the GEHA was only .82" at muzzle. I added an extra rear bolt locking lug onto the Mauser bolt. Using up stuff to make test gun. Any modern steel slug barrel, whether on bolt, autoloading, pump, or break action gun with same muzzle diameter will handle these RE-17 loads. Max loads were all 115gr of RE-17 in plastic 3" cases, all with seals and cushion wads. Can't get no more under the seals, cushions and slugs in 3". Which is why I like 3.5" chambers. With 437 gr Brenekkee and 420 gr in BPI sabot got over 1900. With 520gr Lyman in shot cup 1850. With 600gr Dixie got 1800. With 870 gr hard lead got 1600. This is 24" barrel, so longer barrels will get more. In comparison to IMR4227 loads, these are about the same speed as using 90gr of 4227. But this powder is so much easier on cases and guns, with about .004" less base cup expansion. It works great in 3" and really get the speed in 3.5" cases. The 870gr load is max peak pressure of 16,000 psi. I'll have pic of the Mauser in few days.ED |

Here is picture of my 695 Mossberg bolt action. It is 28ga FH, a 3.25" long brass case. Was a 12ga with light barrel. I also have a heavy 12ga barrel chambered for 3.5" cases and a .500" barrel for my 499HE a real long brass case. Also I am doing my 499HE in a NEF. You can get a NEF with MMouse 500S&W and run my reamer in and get real power.The 395,495,595 actions will work also, as they like the 695 have double bolt lugs and a loading port that can be lengthened. And they have a nice style...Ed |

We get asked about finned slugs for 12ga smooth bores and if they take high speed. Well they'll do just as good at high speed as the locked on wad stablized Brenekkee OK slug I tested in my smoothbore 1887 with long barrel, in first pic. Second pic is a Corbin finned slug I will get and test later. Third is BPI AQ slug I will test, few weeks in the 87. I'm going to test also in a regular smooth bore 12ga slug barrel of medium muzzle size.Ed ![]() ![]() |

Here is picture of the Mauser GEHA shotgun I setup with an Savage 210 rifled barrel. Used a Savage plastic stock also. It is setup with the original 3" chamber. I have many guys who want ideas and slug/load combination's tested in regular rifled slug barrels, so this is the one. Most testing will be 3" plastic cases. Barrel 24" long, .93" regular slug size muzzle diameter. The GEHA was originally converted from 98 Mausers in Germany in the 20s, to 12ga by reaming outl the front lug seats and using the rear safety lug. I added a second rear bearing lug and it handles 15,000 psi loads ok. The cases come out with the weight of the bolt. That will be max pressure used in it, with that slug gun barrel thickness. Example load is 115gr of RE17 in 3" plastic case, with 520 gr Lyman slug at 1850 plus fps. This load expands the plastic case basecups about .005", in comparison, a REM factory Buckhammer expands .010". And we have over 300 fps more velocity.Ed |

Testing some .660" diameter 630 gr hard cast slugs in the red WIN wadcup in 3.5" plastic case. Tested in rifled long barrel in 12ga NEF about 2100 fps. Greg Sappington makes these. They are hollow point. 3" group at 50yds, peep sight, bad eyes. I also fired a couple to see if they'd work in my long brass cased 16GA FH shown in the picture. They work ok, so Greg has a double duty slug.They'd work in 16ga plastic also. The 16ga was held at 1500 as the barrel isn't heavy, on Stevens/Revelation 16ga. Ed |

Comparing brass cases.I tell everybody who are stepping up in power from 3.5 plastic, you can get 3.5" brass cases from Rocky Mtn Cartridge. Here you can see how heavy and nice they are compared to regular brass cases. They also make shorter 3" brass cases also. They fit the chamber tight and are long enough to get some serious thumping power.And they have a super strong, thick , solid head, not a weak balloon head like regular ones on the left in pic.Ed ![]() |

Tested my 499HE in a NEF. Loads I didn't have to full length resize the case, only top 1/4 of case. 325gr at 2600, 500gr at 2150. In NEF got both weight bullets 300 fps faster, still extracted very easy.I got reamer. Just run it in NEF 500 chamber and you got a blaster. And add a little weight and thick pad to the gun.I have a barrel ring to hold forearm along with original bolt, as I added weight there as well as the butt.Ed |

Finally an 870 with longer 1" muzzle barrel. Barrel is heavier than most all add on pump gun barrels, and it is 25.5" long, Something that would really get it on with the slower powder loads we have. Rifled barrel is solid mount in receiver, scoperail solid mount. It is the REM 870 Super Slug Gun. Nice long heavy barrel, and thumbhole stock for handling recoil better. Plastic case 3" slug loads of ours that gets 600gr slugs to 1800-1900 fps, work great in this Like the ones I load and roll crimp in second picture that are setting behind the little vise, and the one in the vise readt to be crimped...Ed ![]() |

Here is a novel slug idea, hard plastic support ring on the front, and a locked base ring/seal. Metal never touches the bores. Work in great rifled and good in smooth barrels. These are steel, lead/copper would do great also.Could be made heavier and different points. Flat point shown would do great damage to game. On the net- ammunitiontogo.com This one is about 500 gr. Second picture is the 499HE to use in redoing the 500S&W, shown on the also, in single shots, etc,for those wanting much more power at 40-50% lower pressures.Ed ![]() |

Some more testing with RE17 powder. I used it in 2.75", 3", 3.5" 12ga plastic, 3.5 and 3.85" brass. I like it the best of all, as well as the real slow powders in our long case with BMG primer. Following tested in Savage-max pressure 35k psi. I took couple of our first made 3.85" BMG based long cases and bushed them back to use shotgun primers to fire off the RE17. Works great, with 715gr jacketed slug and 220 gr RE17 getting 2700 . With 420 gr slug in BPI sabot with 250 gr RE17 getting 3200 plus. Following tested in NEF-max pressure 25k psi. Using 3.5" MRC brass, 715gr jkt and 200gr RE17, got 2500. 420 gr in BPI sabot and 220 gr Re17, got 2900 fps. And we get real good velocities in plastic with half the basecup expansion of factory mag loads.So that solves problem-IE, being able to use regular firing mechanisms and shotgun primers, with large enough powder charges to get hairy velocities at mag shotgun pressures in plastic and higher in brass cases with heavy barrels.A good powder for plastic and brass loads. I see now that Lightfield Co has the Commander 3.5" Plus slug loads with 600gr at 1900, probably in a test barrel. But that is great- nice as it seems we're being copied!!!ED |

So many guys want 12ga sabot type slugs to reload their own. Here is an interesting combination slug available in Europe and they are working to get distributors/stores here. Any interested stores and shops contact them. We need many sources of saboted slugs for reloading. The sabot petals discards completely as slug exits muzzle and locked on base stays with slug, making it nose heavy so it will give decent accuracy in smooth bores.Will work in rifled barrels also. Slug is .629" diameter, comes in 570gr, 700gr, 970gr weights. They're selling these reloader/other loaders only. It is called the US-S slug, and their site is europeancartridgeunlimited.com ..Ed |

The company kindly gave me few US-S slugs to test at high speeds. I had helped him test another slug a while back. He sent me some each of the US-S 570 gr, 700 gr, 970 gr. I tested the 570 gr so far and in 3.5" plastic case in the 1887 smoothbore 35" barrel and in the NEF rifled 36" barrel at 1900 fps. I got that with 130gr of RE17 with one BPGS seal under the sabot on the slug. The bottom of the sabot seal is exactly like a BPGS, so a BPGS added gives double sealing. Both smooth and rifled gave 3 shot 3" group each at 50 yds with peep sights and bad eyes. This slug does as good as advertized in smooth barrels, and smooth accuracy is as good as rifled. My smooth barrel is tight, measuring 723" at muzzle. These should be a great deer and hog slug. Folks need to get after their dealers to work to import these for them to have what seems a good slug to reload... On another note we may have found a guy who is gearing up to make 10 ga rifled barrels. I'll know later this winter If so I will put one on a bolt action and use the 4.1" long 10GA FH case I made or get some like it from RMC..Ed |

Here is picture of the US-S slugs in a lineup with other 12ga slugs I'm testing. Lefteris was kind enough to send me a few of each weight to test. They are the 3 in second row on the right. They are 570gr, 700 gr, 970 gr. I tested 570gr in 3.5" plastic so far. At 1900 in the NEF rifled, and in the 1887 smooth barrel, got 3" group on both. With peep sights an bad eyes.So the US-S slug is great in smoothbores, as good as rifled. My smoothbore on the 1887 is .723" bore at muzzle, a nice tight fit for smooth slugs. The smooth bores Lefteris tested them with are .722" muzzle, and they've already killed 5 wild boars, one shot kills with the 570gr slug. Also if anyone wants a heavy smoothbore new 12ga barrel, .722" muzzle, 1.375" outside diameter to make a great slug gun with slugs like these, and others like the Brenekkes, I have spare one. The US-S slugs are smoothbore accurate in my 87 like the Brenekke KOs.In the picture the left two cases are 3.5" Fiocchi with the Fiocchi magnum primers. I compared that primer to the REM 209 primer and it has about the same strength.Next two are FED 3.5". then 2 12GA FH 3.85" cases, then 3.5" RMC brass, then 3" RMC brass, the 2 WIN 3.5", then 2 REM 3.5".ED |

I got the 700H 3.25 case feeding from the magazine I set up on the Montana Rifle Co PH action. It is singlestack with feed lips similiar to 12ga shotgun clip style magazines I had here. Works great, shown in first picture. Now it is longer than regular 12ga mags, but same setup would do for feeding long brass 12GA FH and long MRC 12ga cases. The 700H 3.25 is 3.9 inches overall loaded length. In picture case is ready to clear the mag lips, then rim pops up under extracter as bolt is moving forward. Second picture is the box used that I made out of two PH boxes. That allowed for extra height and fit for singlestack and riveted together. Used a Savage 210 12ga follower and spring. ED ![]() |
