T/C PTX Bullets in a .45

1794 Views 4 Replies 3 Participants Last post by  Mulder
I was looking at my muzzleloader bullets the other day and got to wondering about loading some of these in .45 Cases. If you have not seen them they are a polymer tipped 250 gr .45 caliber bullet. I was wondering if maybe someone here had tried them or even had some good load data for a 250 in a .45. Thanks, Sean

You could use them, given that they are .451", but why? They will not expand at handgun velocities. They are designed for "magnum" muzzle loaders with velocities approaching 2000 fps.
I know that it was just a question I was kicking around. Sean
If you are bored, try this: Melt the lead out of a jacketed hollow point, and replace it with epoxy. Then load it over ba heavy charge of a fast burning powder. I got a 36gr. .357 bullet to go 2400fps out od a 4" revolver.
I have used some of these heavy bullets successfully in a Volunteer Arms Commando 45 using Unique and 2400 powders and sized to .452.

Just wondering if there are any problems using them in a Colt Govt or similar handgun using a heavy recoil spring.

In an article "Taffin Tests..the .45 ACP" in American Handgunner Nov/Dec 1988, John Taffin implies that all the loads presented could be used in the self-loaders. However, test loads for the 250gr Keith bullets were fired from a 6" S&W revolver.

Max loads he suggested for 250gr Keith were 2400 15.0gr; Unique 7.5gr.
