This is my new Ruger Bisley Blackhawk in .45 Colt. Really like it so far. Just shot it a few times today to make sure it is functioning. 45 colt grabs the attention better than 9mm, that is for sure.
Question: I have high hopes for accuracy out of this handgun. I ran a bullet through the bore and came up with a bore diameter of .4510. The cylinder throats measure .4515 with my calipers (i know this isn't ideal). I'm sizing my bullets at .4525. Will I need to have the cylinder relieved of some material so the bullets can exit a little larger?
I probably won't have time to shoot for groups for a week or two so this is an academic exercise at this point.
Thanks all.
