I have a Miroku 1 of 500 1886 in 45-70. My oldest son wants it. It’s been fired very little and only at targets. It’s heavy with a long octagon barrel. A 45-90 reamer could make it more interesting as I have a Marlin 45-70 that I shoot a bit more.
I think making that a 45-90 makes more sense than sending my Model 71 to have it bored to 45.
I was having a bit of a problem finding bullets for the 348 when I first bought it. Now I’ve got all I need.

I prefer classic.
