Hello - can you double-check me here to make sure I am on track measuring the chamber throats on a .45 Colt Ruger New Model Blackhawk? I removed the cylinder, placed a cast 250 grain bullet into the throat, and then used a dowel to wack it through the cylinder. I used a micrometer to measure the bullet, and all 6 came out at .452.

Does that look normal?

thanks!
