i am want to know the diameter inside the barrel of a 1860 uberti in 44-40. because i know most of the barrel dia are .429 and some are .427. the reason i ask is because i don't want to put a .429 down a 427. i have a ruger vaquero in 44-40 and i want to shoot same ammo in each. the barrel on it is a .429 and i can chamber one in the 1860 and it fits. i just don't wan to shoot it yet.
