@@damienmidanik9680 Actually we're both correct. The ROA came from Ruger in .44 cal.. When the oversized .457 round ball is seated a ring of lead is shaved off, as well as with the .454 conical. Hence a .44. What you're referring to is when the ROC is fitted with a drop-in conversion cylinder. It can then shoot the .45 Colt or .45 ACP but can no longer be sold as an original ROA .44 w/o the original cylinder in .44. Either way, a fine revolver! Mine is the original with 7.5" barrel and adjustable sights I picked up in the late 80s. Which is yours? Lol, unless of course you fortunately have more.
I mean no offense here but none of that cylinder stuff makes any sense at all. If it was a .44 caliber gun, it would use a .44 special cylinder conversion and not a .45 colt. These are .45 caliber guns. I will tell you exactly why they are called .44 caliber though. Calling it a .44 is trying to be historically accurate. Back in the mid 1800s when revolvers were being manufactured, they used to measure caliber by the lands on the rifling and measured the smallest diameter of the bore. This was the easiest way to measure a bore diameter. Today, technology is much different and measurements are also taken differently. We do not measure the lands on the rifling anymore, we measure the grooves of the rifling. Measuring the grooves gives the true diameter of the projectile coming out of the barrel. So the difference between it being a .44 and a .45 is measuring the lands or the grooves. They call them .44 caliber to keep with historical period measurements but by modern day measurements they are actually .45 caliber guns. So you are correct in that we are both right about the caliber, however you are not correct in it having anything to do with the cylinder and shaving lead from the ball. The barrel is still .452 making it a .45 caliber gun by modern measurements.

I enjoy my Ruger Old Army .44 but hadn't heard of the .45. When did they add the .45?
Considering they take a .457 ball and .45 colt conversion cylinders, they are all actually .45 caliber guns.
