My "new" 1889 Marlin is a .44-40. Haven't slugged the barrel but there a difference in the bore size of a Marlin versus Winchester?

I'll be using a .428 200 gn Meister to load some rounds to try it out. This rifle has the cleanest action and barrel I have ever seen, but exterior shoes pitting that was cleaned up long ago. I can barely read the stamping on the barrel and there is NO caliber designation.

Another variation? Parley Bear identified the DOM as 1893.

Thanks for any information.

Not sure how Winchesters run, but I believe they are about .427". Marlins usually run a bit tighter on most older Marlins that I have slugged, but the .428" bullet should work well.
Without the caliber marking on the barrel, I hope you did a chamber cast, or are somehow sure it's not a .38-40 instead of the .44-40? There's only a couple hundredth's difference between the two. The caliber markings can be very faint on these early guns, and with a bit f pitting, or roughness, they are unreadable.

MM93 is correct. There is not a lot of difference between the .38-40 and .44-40. Both Winchester and Marlin had some variences in the bore size. The only way to be sure is to slug the bore. Parley

Also slugging the bore will give you a better idea on what to size your bullets to.
