My revolver is a .44 special three inch barrel Taurus model 441.
If one's revolver is going to have oversized cylinder throats at .4335 or .434 diameter, and the gun's rifling is only .429 diameter -- can you expect ignition blow-by gasses to push past the bullet while enroute to the barrel forcing cone???
Is there the possibility that the cast bullet may be a bit off center when entering the forcing cone into barrel rifling??? This could cause bad accuracy if this is indeed what happens.
I've thought about having a seating die made up in .4335 diameter, but this seems excessive diameter to ask the bullet to enter the smaller .429 rifling. I'm not keen on doing this as the strain on the gun is going to be a bit too much. There could be a lot of lead shaving build-up in the forcing cone and rifling.
Therefore, wouldn't it be better to just make my cast bullets in .430 diameter and perhaps make them with a good hollow base of about 1/4 of an inch...hoping this takes care of the excessive oversized cylinder throats by the bullets rear base bumps up to slip through the cylinder throats while the front portion of the bullet remains in hopefully perfect concintricity to hit the focing cone area and the bullets entry into the rifling.
Any thoughts on this scenario, anyone have the same problem with oversize cylinder throats.
