I recently acquired a 1895 Cowboy Action in 45/70. After lapping the barrel to smooth it up I ran a slug down the barrel. My micrometer is packed away so I measured it with a friend's digital caliper and was surprised when it read .4575. Hmmm, I keep reading Marlin bores their rifles a bit over instead of under. I'm wonder if the new Marlins are being built with tighter bores than earlier guns. Anyone else experiencing this?
Been expecting to need a .459 or .460 mold but that may not be the case, now. Guess those Lee molds may not be too small after all.
Any experienced input is welcome.
