Hi
Last year, I got a Springfield Trapdoor 1884.
I spent "some time" to clean it.
So here I am with that gun after cleaning...
I shooted with some .459 405 grains bullets...
WOW only KEYHOLES . . . . . . . . .
I slug the gun: WOW !!
- groove diameter: 0.467
- bore diameter: 0.461
What would you suggest as mould diameters ?? I was thinking a a custom mould with some .468 diameter....
