Bore diameter

Posted by Thomas Jacobson on Sunday, 12 December 2010, at 5:22 p.m.

I own a M1884 rifle, serial #472632, that is in unissued condition. I recently ran a lead ball thru the bore to measure the diameter. Using a paper wrap around the slug, measuring with a caliper, then deducting the paper thickness x2, I get .455. I always assumed trapdoors would be in the .460+ area. Would a bore actually be this small?
