Typically we want the throats of revolvers to be a couple thous over groove diameter correct? I have been reading and seeing that some have tested what happens by shooting some loads without a barrel screwed on(I think they were using Dan Wessons). They found that the bullet, sure enough, bumped up to fit the throat.
So, my question is how this affects loads if you choose to shoot jacketed ammo. Do the jacketed bullets also bump up? I would think they would given the amount of pressure behind them. I know they are not as soft as lead, but they are not as hard as steel either.
If they do bump up, say we are talking about 44 magnum that had its throats opened up/evened out to .432", then is it bad for that jacketed bullet then to be shoved through the forcing cone and squeezed down to .429" by the barrel?
I have to think that it's not really an issue because I do know that a lot of guys who shoot cast also shoot some jacketed bullets from time to time. It just made me wonder about it all when I was reading and started thinking about it.
