Re: An unusual 24ga W. Collath Double Rifle

Quote:I know that. Per my chamber cast above - groove is 597"
There wasn't one...
...it was the 20-bore BP rifle cartridge, brass case!
If it chamber-casts .600 NE then groove diameter might be .615 to .620?
24-bore should be groove diameter .577 to .580
Not much help, sorry.
