I'm thinking it depends on the bullet maker. I've seen jacketed and plated at .451" and .452". Then LRNFP at .452" to .454"!
The one's I have are .452"[MBC] and .453"[RedLine]. Reason for difference? The way jacketed/plated works in a barrel as opposed to lead. I think? The way the bullet seals at ignition for proper, hmm, can't think of the term. Dang it.

As dangerous as it is to be lured into guessing at terminology (as a newbie), the thing that comes to mind is "pressure check," which is (I believe) a lead bullet feature, kind of like and O-Ring in the cannelure area...? Might have totally butchered that, but I tried...

not sure I can speak to the twist rate and accuracy question, but I bought the BBB in 44 mag cuz I have the ruger SBH Bisley and it just made sense. The 45colt is no slouch so if you do not have a companion pistol get both, one in 44 mag and one in 45 colt.
I seem to be able to get 2 inch groups at 100 yds with xtp over 4227. This rife seems to be a real shooter as 2 inch at 100yds in this pistol caliber is good for me.

Great guess, E^2. You're thinking of a "gas check", which is a metal (often copper) base cap for lead bullets that "provides a thin layer of harder but still malleable metal on the base of the bullet that obturates to provide a seal and prevents the propellant gas leakage that causes gas cutting, and helps the bullet grip the rifling."

See, I knew I'd screw that up! I was close, though. Well, not really.

Sort of.
