Got a 1894CB yesterday in .44-40... tried to slug the barrel with a .430 bullet and it came out at .429...is it safe to assume Marlin used the same barrels and just changed the chamber reamers between the .44-40 and the .44 Mag

Yep.. that's what I was always led to believe...that's why I'm thinking they used a common barrel for both calibers and just changed the reamer...but of course I could be wrong......

Teal, your 1894CB 44-40 . Was it one of the original run or was it a factory conversion ? In "SHOOTING LEVER GUNS OF THE OLD WEST " by Venturinohe was sizing .427 for his 1894CB 44-40. Thats why I ask if you possibly had a conversion.

Heck,
I would prefer the .429. It would make it alot easier to get correct sized bullets for. Jacketed .427 are hard to find!!

When I first got my 1894D, I slugged the barrel 3 times using .451 roundballs for my old cap & balls. Each time the micrometer read .4285".

I've noticed that cast (or jacketed) bullets of .430 or larger won't chamber due to a tight chamber neck. So, I size my cast to .429 which loads fine. I was a bit worried about some of the old High Velocity type loads using a .429/.430 bullet with the .4285 groove diameter, so I special ordered a .428 bullet sizing die from Lee and after using case lube on 'em I resize the jacketed bullets to .428 and they shoot fine.

Any know what the groove diameter of a 1894 in 44 Magnum is? I haven't had the chance to slug one. BTW, just for reference, a Rossi Puma in 44-40 slugged at .430.

I don't have one, Willy, but Marshall over at Beartooth's claims they are .432, and that the best fit bullets for the 444 are that way as well.

This subject came up some time ago on the old Marlin Talk forum, after I mentioned that I had checked new Marlins and found them ALL to have .429 bores.
Lots of people said no way, or other less polite replies, but it's true! I asked at my local dealer if I could check the new Marlins he had, and all were .429", so I think they share a common barrel!
