Here is a Midland break action a guy is doing in 24ga FH.
Here is old catalog picture of different stuff used in old days for shotgun loads. Some would be hairy in brass cases
Here is picture of a MN a guy is doing 585HE in.. It is singleshot. Redid bolt handle, mounted it on the bolt further back, so the port could be lengthened for our long case. Also puts handle back where it is easier to grab. Needs, more shaping, polishing, blueing, scope rail added.
Here is another picture of the 585HE with great looking stock. Nice looking wood. Ed
Our friend Brian from the far north went to Africa with his 24ga FH he did in a NEF break action and got 3 nice buffs with it. Good job.
Our 585HE, 700HE and the great 12ga FH are now in the new COTW book published in Oct, now out for sale,
We now have our target 375 HE cartridge, made by necking down our 585 HE. The other couldn't make enough 375s, so we started our own. It has different shoulder taper, length, neck length, improved over the other one...Got a bunch guys doing it, most into the 2 mile shooting venues, We're making cases, testing, reamer prints at reamer guys, we are getting guys going. King of 2 mile shoot last year really got the interest booming for 375 necked from our case,
Here's how we size and seat 375 HE, a simple die, a 1" die, no huge dies needed A die we can make with resize reamer from reamer guy, a regular die body,then pass on to the next guy, one reamer can make whole bunch of dies for folks.
I do primer work separate, not in the press.That way I can clean pocket, check flash hole,....... SO First with lock ring set, I size cases.
When coming back out of dies with case, we notice the case still well centered, held straight, when it is down as far as the length of the 375 HE neck... IE the sides and shoulder corner still supported tight. About .35" down.
So we put washer or another lock ring on, same thickness as neck length, below original lock ring, screw down tight tight in press,
Dies had a 5/8 x 24 thread in top, had powder fill bushing and other stuff same thread, reamed out from bottom to set bullet height, with ram, case,and bullet up,
After priming, loading in the powder charge, we carefully start(boat tail makes it easy) bullet in case by hand, slide up in die, into holder, raise ram to to top, bullet seated perfect. Die can have different thread in top as long as big enough to hold seating bushing of some kind , that can be made from many items.
These target bullets held in by strong neck tension, no crimping needed, and notice bullet point will get no marks or dents, fast, easy, no 380-500 buck special dies. Bushing centering bullet on ogive is very accurate.
OVER 900 375HE cases piled behind presses getting done. About 600 on another bench nearly ready. Small batches in shelves.And we will do more.
All 375 info, prints, specs, pictures, load data, etc, is public domain, worldwide, for any target, hunting, etc, use..Ed
Here is picture of a brake on 12ga FH with real hot loaded hollowbase lead slug, brake needed more clearance for the expanding slug.
Here is the before and after of 375 HE cases, 2 on left necked, 2 on right formed in hydro die after necking..
Here is pic of 416 HSM second from left we are experimenting with, going to see if we can make the ultimate 416 ELR case. Can be 3.60" to 4.00" long, a long one pictured. Holds over 280 gr ball powder under bullet. In the picture, 1st case is 416 HE, 2nd 416 HSM, 3rd 375 HE, 4th 378 WEA.
416 HSM will get 400gr to 4100 plus without needing BMG action, 470 gr 3800 plus , it may be the ultimate target, singleshot 416.. Case will work in fat bolt actions, with heavy enough barrel to have good, milder, barrel harmonics and srtill be under 50 lbs. A lot of the 2 mile type shoots are adopting 50lb limit.
Here is picture of the 416 HSM fireformed once, next to bmg case we make it from and as we improve wildcatting process next few weeks some specs may make small changes, now from base to shoulder is 3.45", case 3.97" long. Ed..
Manson has 416 HE and 408 HE prints, as well as 375 HE He can also make you a resize die reamer from that info. We got 700 cases in 416 and one more pass if 408s wanted, , Going to do lot more cases for these 2 sizes also, Questions, PM or email. ph 989-644-5228..
Here are final specs for 416 HE. Length 3.32", belt diameter ,655", base dia .635" , length base to to shoulder 2.860" , 30 deg shoulder.Ed

Guys asking about strong economical bolt gun to use for 28ga and 410 ga and 32ga with brass cases and higher pressures than plastic cases. They can use a MN bolt action, here is pic of one with our 585 case in the action.Guys can get Magtech brass cases or have RMC make them....Guys can make 32ga case from 500 NE, 410s from 9.3 x 74 brass, etc..
Here is picture of our 416 HSM case sectioned next to original BMG case on the right sectioned, to show that we still have enough thickness in the sides to handle high pressure, in a case with 310 gr capacity..We are getting the wildcatting work set up so we can do at least hundred a month. We have lots of 585s, 375HEs, 416 HEs, 408 HEs..... And working toward getting 416 HSMs in big numbers.
Here's comparison of 416 target cases, 1st 416 HE, have whole bunch. Second is model of what I'd have made on medium machine, if I could, the 416 HE Long. It has capacity of 230gr.. Third is our 416 HSM which we are working on making by wildcatting bmg cases, And if had run long cases, make longer 375 HE necking down 416 ..
Bryan Litz just recently shot 3 shot group at 2 miles using Paul Phillips heavy barreled, target rifle built by Lethal Precision in 375 Lethal Mag(585HE necked down, very similiar to 375HE )... It grouped 17.5 inches tall by 22 inches wide.
Applied Ballistics shooter Mitch Fitzpatrick just hit 3 of 5 at 3520 yards, weekend 10-13th at Valdina Ranch , west of San Antonio. Also used the 375 LM case similar to our 375 HE Great shooting at the 2017 World's Longest Shot Challenge. Ed

The 12ga FH case now is in the new COTW book on last page in the wildcat section, I think page 324. They gave good credit to Rob for the idea of that case....
The model 416 HE long case in middle, hydro formed one,
has case capacity of 240 gr, and the 416 HSM in picture,
on the right, we fired a case twice, capacity is 320gr.. Ed..
More info out now; short, fat cases sticking, pockets not lasting as expected. Trying to get best speeds the things raising pressures are bad case proportions, too sharp of shoulders, too fast of powders........... and debth of the bullet into the powder space, as shown in the picture below.. My 375, 416, etc testing, bullets loaded like bottom one, in longer freebore....Ed.
For big long cases our testing is showing that the 416 easier to get powders to work with, less problems .. Maybe building a target gun,don't have 375 barrel all ready, maybe go 416....
We got cases, 416 HE and 416 HSM, as well as 375... CEB and others will have bullets...CEB will be doing .416 in 450gr, 475gr, 500gr, 525gr and 550gr
Got sent 5 thick sided sample cases, same OD base as 585/375.416 cases, same belt, just .180" longer, did a 416 HE, chambered extra barrel , cases stick over 50k. They have about .042" total taper, .021" per side, when I necked couple to 416. That is a lot of taper , twice the taper of my 416HE...hanging up at 50k..
I could maybe go to 65k with these if we made taper with ..012" - .016" more taper to each side, but that is no way to build target cases. I'd have to crunch down case shoulder diameter. And would look like 30-30.
And crazy part is, the case has enough brass material to thin up sides and stretch them way out to 4 or more inches,, They weigh 150 gr more than our 585/375/416,, but with real thick sides they actually hold less than our 416 HE with thin sides, that is .180" shorter...Our case does 65k ok without sticking..
And we can make super long 4" cases work if we had means to get them built, as we have 15 powders slower than HBMG.Here is pic of thin and thick sided cases, sectioned for comparison.Ed..
