Hey guys...

whats the rim THICNESS and neck/wall thickness of the bertram, mast/bell and HDS brass?

I am asking for these, in case you have any or all

not the diameter (.750)... the thickness.. I think the rim is .063 and the neck/casewall is .010

Jeffe,

I do not have any of the modern stuff, but here are some from Kynoch and also Eley.

Kynock
577NE rim thickness .046"
mouth dia. .603"

Eley
577 BP rim thicknes .043"
mouth dia. .603"

.603 - .585 = .018/2 = .009"

jeffe,

What'd you say. I can see your mouth moving but I can't hear a word. Speak up buddy.

Anytime you want to waste powder and save your shoulder, I'll volunteer to lend you my shoulder. I didn't want to over step my invitation, but I'd of liked to shoot that cannon more. It sure gets your attention. And blood flowing! Impressive to say the least. That is officially the largest cartridge I've had the pleasure of shooting.

Mark,

I've got one new Bertram .577 brass. The case thickness at the neck is .012-.013. The rim thickness is .046. But, this might not be correct, considering it is Bertram. All depends what mood the makers were in that day.
