The cylinder throats on my .45 Colt Ruger Bisley measure .451 and the throats on my
.454 Alaskan measure out at .455 diameter.
Shooting mild 850 FPS to Ruger type loads using my hard cast lead .452 diameter bullets,I get no leading in my Bisley or any of my other .45 Colt revolvers or rifles in the barrel.
Looking through my Lyman 49th loading book and my Speer book they recommend .451 diameter
bullets for the .454 Casull and of course .452 for Colt .45
When I shoot any of my hard cast bullets through my Alaskan I get leading,like I have mentioned before,in the area of the bore starting right after the forcing cone exit.
When shooting jacketed bullets in the Alaskan the bore is clean with no signs of heavy copper build up.
What is the correct throat size of the .454 Casull and why do the loading manuals specify .451 diameter bullets.
Some have said it could be a tightness in the bore where the barrel is screwed in the frame on the Alaskan. The short barreled Alaskan frame looks to be machined as one piece.
Is the barrel an insert that is pressed or screwed in and how would they grab the barrel insert to screw it in?
