Hi Rob,
Once you discover what your original chamber was cut to fit, you can have Dave at CH4D build you Dies to fit it as well as find original vintage cartridges to go with it properly if you wish. Once you cut the chambers it is no longer original nor will it ever be again. There is no turning back, if this is not a expensive gun or has no historic value & your not worried about resale value and it is just planned to be a shooter and access to factory ammmo is necessary then opening the chambers might be the way to go for you. I understand your concerns, I used to think the same way until I thought about the history of the fine old guns and the fact that they have existed for around 100 years without the chambers being messed with. Then the satisfaction that comes with mating correct ammo together with an old gun that may have been years since it was shot last & making the correct ammo to fit the gun is half the fun! Your Call, just some food for thought.
