.45 auto bullets in a .45 colt case?

[Goose Guy]

Asking for a friend:

Say someone loads for .45 acp with 185gr. plated bullets and would like to use that same bullet for .45 long colt loads, would it be possible? Both appear to be .452 in diameter, as far as Berry's site goes. We figure the lighter bullets probably won't be as accurate in the SAA as a 230 or 250 grain load, but just for fun, low recoil plinking loads it would be simpler to just use what is already available on the table. Also thinking about some .454 lead round ball loads, but that's for another day.


TL;DR - can I take the same lightweight bullets I run in .45 auto loads and throw them in .45 LC loads (with change in powder charge, of course)

Yes

Short answer is yes. Longer is yes , providing that particular .45Colt's throat and bbl diameters otherwise give decent accuraccy with .452 bullets of traditional weights.
CAS shooters who are competive oriented , yet still use .45LC commonly use bullets as light as 160gr.

Cool, that was easy. Thanks guys.

I shoot 200gn lead round nose, flat point in

all of my .45's. 1911, S&W25, Pietta 45 LC conversion and Marlin 1894. I use 7 grains of Unique which is really mild and is accurate in all of the guns.
