I'm assuming those sizes listed are groove and bore diameter. For a minute there I was like "why is your barrel tapering?"

[drdarrin@sbcglobal.net]

Yes they are.
A tapered barrel would be interesting.

I purchased a 45-70 last week, a 1999 Marlin 1895SS and slugged the barrel tonight. It measures 0.4574. Looks like it should be easy to cast my own bullets or to buy cast bullets for it.
