Skeetx, Mike, I know what you mean about the 12 ton shop press, I went through all that learning about making cases for my 11.15x 51R, without cutting my few 43 Mauser cases( reduced 8x50R Lebel and blew it out, added rim to 7mm mag after turning belt off). That exercise showed me the easiest way is to move the rim on 45-70 to approximate the MB. I helped my cousin make 43 Mauser cases the same way, but with 45-90 cases. It dawned on me during all that, that 45-90 cases should work very well for 43 Spanish by simply adjusting the rim to fit the rifle, if required. I haven't tried it yet, because I have a quantity of Original 43 Spanish cases. I should try it, seeing that my Spanish cases are folded head and Berdan primed. BTY 45-90 cases should make fine 44-77 Remington cases, the same way as 43 Spanish. The 348 case is the "school solution" donor case for several cases that are now better served with other donors. When Askins wrote his book, many cases were not available and he selected 348, because it was the best choice at that time( it still is, for some cases). Mike

Mike YES!! We speak the same language I had a Sharps #3 Business Rifle in 44-77, what fun. It went to a friend in California. I used .446 bullets in it and .439 in the 43 Spanish that I have. I made case body swage dies from diesel engine wrist pins, WHEW!!

AND I would only do 3 cases per day and then let the die rest. I wanted to swage the heads down to size and NOT use a lathe like some folks. Mike

Skeetx, Mike, I cut a groove, the width of a parting tool, ahead of the rim. This groove was to the diameter minus .010" of the target casehead. This groove was in the solid part of the casehead and prevented closing the primer pocket and flash hole. Having to reopen the flash hole and primer pocket wouldn't be earthshaking, but it would be a troublesome operation. Mike

2 years ago I accompanied a friend on a Maine moose hunt, where he took a nice 2 1/2 y/o bull with his cape gun. One 90 yard shot from the 11.5x50R broke its spine, and he finished it off with a 16 ga round ball. He used a pretty-standard cast bullet in the 11.5, 365 grains IIRC. Made his own cases for the 11.5. I'll check with him to see what he used as the parent case. I think it might have been the Lebel, but I could be wrong on that.

OK friends, I picked up the Münchner Büchsflinte this afternoon. I should slug the bore myself, as I have some 50 caliber round balls, but here are the measurements from the chamber cast: Groove 0.471 Case mouth 0.513 Base 0.525 Rim 0.605 No shoulder whatsoever.
These dimensions are a little bigger than the 11.7 mm Danish. A new 45-70 case drops right in, but there is a good deal of radial clearance. The closest thing I can find is 12.3x50R Mauser Straight. Matches the rim for sure.
This gun opens by rotating the forearm clockwise. There is a wedge that holds the forearm in place. The shotgun barrel measures 16 ga. IC.
What do you think?
PS: New lead slug measures 0.470, no real change. Very wide grooves.

ligonierbill, How deep is rim recess, does it need Mauser base type rim or flat? What is case length? Mike

Rim recess is about 1.5 mm, flat. Case length is a little difficult to measure from the casting, but it is 50-51 mm measured from the base (not including rim thickness. Seven grooves and lands.
