I was under the impression a threaded breech plug was one of the strongest means possible. Isnt that essentially how the Welin breech block works? That concept was used on 16” battleship guns
I shoot 50’s, have three of them. Freeze the video at 5:03. Just take it in for about 5 full minutes.
That threaded stub is
maybe about 1/2 as long as it is wide, and the first two full threads didn’t even strip, as I see it. What does that mean. To my thinking, that’s really a problem, to engage such limited threading.
Kentucky believes the Slap muzzle fire ball was large indicating hot loads but it could also be that they simply exit the barrel before the powder is burned like light bullet 22-250’s, because they are light, and that one of the Slaps recorded with a smaller flash was the exception. I wonder what the brass looks like.
If this threaded barrel was offered to me as pictured with that stub being a proposed “tenon”,
just to hold the barrel on a receiver, I wouldn’t feel very comfortable with its proportions for even
that limited purpose, let alone containing pressure repeatedly.
This is just my opinion as a shooter and rifle user, but I’m going to want more steel in contacting engagement, and behind the contact surfaces, than I see, and not in angles to each other that rearward recoil thrust over time can work to lessen, either.
My personal opinion is if my action is going to fail, the brass better not still look good.
I think the interrupted threads used in cannon breeches, although also angled, are taller and deeper relative to their diameter.
