I recently got a ca. 1924 Colt New Service. I can insert .452 dia bullets from the front of the cylinder no problem. Does this mean I have oversized throats and should use .454 bullets?
TIA!

No, It Does Not Mean That. What It Does Mean Is You May Want To
Measure the cylider throats with a plug guage to find the correct ID of those throats.
In those days .454" was the correct diameter for 45COLT revolvers. This does NOT mean you can't use .452" bullets today with every satisfaction. You may well be in for a most pleasant surprise.

Wil,
Thanks. In fact I did try .452 dia and the accuracy was good. Well, since .454 is harder to find in these parts maybe I'll just stick to .452.
Thannks again.

My Colt New Service made in 1906 shoots .452" diameter bullets very well. In fact, I had planned to open up a Lee Mould for this gun -- even had the grit set up -- but decided to shoot it first. It grouped so well that I decided not to fix what ain't broke.
This same gun (with 7 1/2" barrel) shot about a foot and a half high and a foot to the left at 25 yards. Since it had been refinished and the markings almost polished out, I decided to replace the razor-thin front sight with a thick slab of steel, which I filed to get elevation, and then opened up the rear sight notch to correct the windage. I can sit on my porch with this gun now and punish a gallon can on the bank of my pond about a hundred yards away.
