Some interesting shooting with 4bore.
Double 760gr ball load of 1520 gr total, at 2300 fps.
A buck and ball load, 6 45cal lead balls, 133gr each, and a 760 gr ball on top, 1560 gr total, at 2300 fps.
Both loads 100gr BlueDot under 225gr Re17, In the turned brass cases, with shotgun primer.Recoil manageable, and like a big push. The sound isn't a boom like regular shotguns, but cracks loud like big bore rifles,at least twice as as loud.Ed

I got my 20ga FH 3.5" brass cases from RMC. The case capacity in water is 234 gr. It holds 215 gr of dense ball powder to the base of 490gr 20ga hard lead slugs I have. These cases use a 209Mag shotgun primer, and I have mouth ID set up for .620 slugs as the slugs and sabots I have are that size. These cases will work good out to 35,000 psi, without extreme expansion or resizing problems. Load of slow powder will get 490 gr to 2500 plus at 25-27,000 psi, 6800 ft lbs, using the 30" barrel I'm getting to put on the FBW Model L falling block. ! also have a case of the 3.5" factory Hastings SPW, locked on sabot, loaded rounds to use.Ed

Here is pic of the RMC brass 20ga 3.5" with Hastings 3.5" factory plastic case loads, and 20ga Hollywood dies. Also slugs, Dixie 490 gr, Hastings SPW and 900gr jacketed in the one case. Second pic is the FBW Model L setup that will have 20ga 3.5" chambered barrel in a second one. This 1st one is in my 585HE.It is falling block in one piece thumbhole stock, an idea I come up with on my 4bore falling block. Second Model L will be built same in 3.5" 20ga. EDd

Transition, biggest to a smaller, in putting falling block actions in one piece stocks. First one was the 4bore, the big one in picture and after it was done I got a FBW falling block and soon figured out I could do the same with it. It is chambered in my 585HE cartridge. And it is pictured above with the cases. I built the 4bore, from blocks of steel. The FBW is the Model L, and I'm doing second one in 3.5" 20ga, to use brass and plastic cases. And maybe later on when I find extra 700 barrel we'll do my long 700HE in FBW....Ed

Here is picture of FBW Model L in one piece stock, compared to a FBW Model S in 2 piece stock. Both are chambered in my 585HE. These two plus the Wickcliff 76 and Ruger #1 will easily handle my 585HE with proper weight and thick pads. These guns have rimless extractors and my 585HE goes in and out with least amount of metal removal from the feed trough, with much more power. The Model L will have a 3.5" chambered 20ga barrel to use 3.5" MRC brass cases and Hastings factory or reloaded plastic cases.Also I'm working to put a Wickcliff in 1 piece stock.Ed

Here is picture of a bolt action a fella on Practical Machinist built for an 8ga. It has 4 rear bolt lugs. He used section of 20mm barrel for barrel.. Real nice. Idea would do for 10 and 12ga also I think. Has an aimpoint sight. Ed

Here is picture of the fella firing his bolt action 8ga that he made. He uses the super strong, heavy duty, plastic cases like we are using in the ones we made by boring out NEFs to 8ga.Ed

Some have asked if the guy who made above bolt action 8ga does them for others, but he only did one for himself, and isn't a manufacturer. Here is picture of a cast .504" slug BPI 12ga sabot a guy made a few for me and it has good accuracy with our slower powder loads, with the sabot working ok. Slug is 440 gr and hard alloy cast with decent meplat for good penetration.But it isn't too blunt so it has good longer range capabilities when you get the speed behind it. Soon be the deer season and guys are still hunting for their ideal 12ga sabot/slug setup for loading their own.BPI is supposed to have a new sabot this year..Ed

The .504" lead slug I show for using in 12ga sabots is one cast for using in .500" cases like my 499HE, by sizing it after casting. Tried it at the .504" diameter and it works in the sabot also. So it does double duty, unsized 12ga sabot, sized and lubed in .500" use. Some like short cases in big calibers, and have put up various ideas. First picture is 12ga brass cases, two 2" long and other 2.25". Cases made by shortening our cases we made by putting rims on bmg brass. These can be used in Savage 210 and feed from mag box. Can use 2.5" Magtech brass shortened so case and protruding slug will be 2.7" overall and feed from magazines of Savage & Mossy bolt guns. With 2.25" case you can get 600gr to 1800 at least.Ed

Have had a bunch of different guys shooting the 4bore with light 11,000 ft lb loads. All say it is a tremendous thrill. Simply the greatest shooting ever.
So many have opinions on what is a real big bore. I think really big starts at .585........ So in that vein I have made the 585 Hubel Super Magnum, 585 HSE, giving a nod to necked cases.Also can make the 620 HSE for 600 guys. This is my only wildcat base case with a neck. Base and rim are .750", shoulder is .720". and case is 3.7" long. Power in the range of 14,000 to 17,000 ft lbs. Can be used single shot in the PH, the Savage 210, the Enfield. Not for mass production by me, cases too hard to make. An experiment with necked cases. Picture of the case later.Ed

Any chance you would do a book on this topic? It is hard to follow it all with so many entries now.
It is very fascinating and inspiring.

I'm not a writer and don't have the means to put out a book, if I was. I type with half a finger, no co-ordination, and many mistakes. 20 gauge-- Fired factory 3.5" plastic cased Hastings 395 gr locked on sabot slug in 20ga with 30 inch barrel and got 1900 plus fps. Same sabot slug in RMC 3.5" brass case with shotgun primer, got 2500 fps. Case bases didn't expand. Load of 150gr RE17 slow enough getting to peak pressures is easy on cases. Dies work with both case types.Ed

20ga testing- 600gr slug in RMC 3.5" brass case with shotgun primer, 2300 fps. Cases very slight base expansion. 12 number 1 buckshot, about 510 gr worth, 2000. Glued a 20ga card in the brass case over the shot. Few more guys are around having fun shooting the 4bore this summer. Ed

There are fellas who have and are planning on doing hopped up loads and cases in the Greener GP, Martini type action. Here is picture of one done couple years ago by Aussie guy on NitroExpress forums. They need heavy barrel in place of original. It has a rifled Pacnor barrel and weighs about 9 lbs. In my measuring an action here, they will feed a 3" brass case with a protruding slug, like the cast Dixie or the Henson jkt slugs. I like the looks of these old classic guns. And they are strong enough with 3" RMC brass to get 730gr slug to 2000 fps...Ed

A fella cast me some 10 and 8ga hard alloy lead slugs. 10 ga 1050 gr, 8ga 1320gr, fullbore, have large concave in the base. Should need little more hollow in the base for longer range accuracy. Just hard alloy, not heat treated. Nice design, one wide groove, for lube if needed. Fired one in NEF 8ga below, with heavy 3.3" plastic kiln case, 1700 fps, 9000 ft lbs energy. Entered backstop straight at 40 ft.Have pics of the new slugs soon.Ed
