Seen the prototypes, can confirm, @GUN-DMC swapped brains for more balls.

The reason I settled on 3 1/4inch was that that was the longest case that would load into the martini action.
Yeah, because shoulders are stupid anyway and need to be punished, ay? LOL. I’m not going near that thing.
Intercontinental ballistic shotgun of mass awesomeness.
much more productive and interesting.Wouldn’t you be better soldering them or better still silver soldering?
Soldering or brazing will likely anneal the brass.
Why not just use the brass shot shells?
Yes, silver soldering would but I doubt soldering would. Solder melts at about 200c. Too low I think
I won’t be soldering at this stage, I will try the epoxy next if I find I need to beef it up or tap a thread on the case and screw the heads on with loctite.
I’m not using the magtec brass whole for this because the walls are to thin to to seat bullets in them without making a die set I think, plus 2 1/2 inch cases are for girls and antiques.
I really want a 12ga from he’ll and I really want a greener GP 12 bore rifle. So this is the compromise between the two.
Plus I like to tinker!
I’d be concerned about the pressure if you are planning to load heavy slug loads as you suggested. Having trouble believing the join is going to hold up.
Me too . That’s why I suggested soldering
Epoxy would be stronger than solder I reckon and there’s no risk of annealing.
The 50bmg case still has it head it’s only the rim that’s turned down and the primer pocket of the magtec brass fits inside the bmg primer pocket.
I wouldn’t be too worried about pressure. The case is really supported by the chamber which is what really takes the pressure. The case is just there to hold all the components in place.
However maybe use a long piece of string to fire the gun the first time.

A very long piece of string…
Yeah long string and start with a trail boss load before moving onto 2218 or whatever the ADI bmg powder is called.
I think solder will be several times stronger than any epoxy. Yes the chamber takes the pressure but what if the epoxy fails at the case head/join & leaks. Where will the gasses go?
Shit yeah! Max power charge load her up and get the strongest most bad ass shotgun you have @GUN-DMC ( not the russian door bell )
Safety third!

Are you just trying to creat a rim so the heavier case works in a shotgun chamber?
Correct mate, I just need something to headspace and extract from.
