Anyone know offhand what bore size is on Henry 45/70 single shot?

[bedbugbilly]

I'm strongly considering a Henry 45/70 single shot - primarily for fun shooting with both BP and smokeless loads - not pushing it hard - a "play gun". I couldn't find anything on Henry site - starting to look at molds but need to know what I need. It will strictly be a cast shooter.

Anyone have one that they have slugged the bore or know for sure what Henry makes for the bore size? IIRC, I thought someone posted about it here sometime in the past year or so but I couldn't seem to dig it up.

Many thanks!

It's exactly to SAAMI specs, with a .456" groove diameter.

Mine also slugs at .456, shoots .458 gas check 475 gr. Very accurate with zero leading.

thank you guys for the info, it kind of seals the deal on a new 45-70.
