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 ![]() |
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 gets the speed in 3.5" cases, as in 3.5" cases,as seal/wads about same, extra length for powder. The 870gr load is max peak pressure of 16,000 psi. Muzzle pressure is about 3500-4000 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 cast slug at 1850 plus fps. This load expands the plastic case base cups about .005", in comparison, a REM factory Buckhammer and other super mag turkey and goose loads expands .010". And we have over 300 fps more velocity.Ed ![]() |
Hubel,
I think I asked you before. Have things changed, do you have any plans with all that you've learned discovered and built? Tom |
Just to keep on experimenting and shooting.
And promote big bores, including my 585 and 700. Nothing commercial as I don't have the big dollars to set up manufacturing.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 ![]() |
