It's my understanding that when cast bullets are used, the bullet should be .0005 to .0010" larger than the barrel groove diameter. And ideally, the cylinder throat will be .0005 to.0010" larger than the bullet.
I have a SBH with a .430 grove diameter barrel, but the cylinder throats are oversize to .436. What is the impact of this level of oversize throats?
It's also my understanding that you select the bullet dia. to match the cylinder throat dia. and not the barrel diameter. But .436" throats sure makes that questionable.
