1860 Colt vs. Remington New Model chamber capacity

[Oregon Bill]

I have had several of both over the past 40-some years, and never actually measured the chamber capacities of the two designs. I don't know why it never occurred to me to do so. There is probably not a significant difference, if any. Just thinking about this stuff while trying not to scratch another cap and ball itch.
It's the same old story: Love the sights and ease of cylinder removal with the Remington, but hate how that trigger guard abuses my knuckle. Love the lines, grip and pointability of the Colt, but struggle with the sights and getting that dang barrel wedge to fit right yet come out easily.
