Let's just say "NO". Go out and buy a proper set of dies. Don't try to take shortcuts in re-loading.

I've loaded hundreds of them.

You neck size the .45 Colt case with the ACP sizing die.(Just like you would with a LEE loader)

Expand with the expander die just enough to start the bullet.

Seat carefully, and crimp by running the case part way back into the sizer die, just enough to remove the belling.

It's definitely not a good solution, but it will work until you can get a set of .45 Colt dies.

I would be afraid of crushing the side walls during the crimp because they don't have enough support when pressure is applied.

"But you can not use the sizing die. The 45 colt is too long."

Actually, the length difference is not a problem, many of us have routinely reloaded .357 w/.38 spl dies and .44 mag w/.44 spl dies. I've even reloaded a good bit of .444 Marlin with .44 mag dies and did "FL" sizing to do it. The real issue is case diameter and wall thickness, not length.

Few straight wall cases ever need FL sizing but if we push a case fully into an open top sizer it can easily be done.

No seating/crimping die I've ever used was sufficently tight to prevent case wall bulge if crimping is massively over done.

No way you can use 45 ACP dies for 45 Colt! The die interiors are too short. The proper bullet diameter for your revolver can be determined by measuring the chamber mouths on the cylinder (the side that faces the barrel!). I have a Ruger Bisley contvertible 45ACP/ 45 Colt. I had the cylinders bored out to .451 (?) inch for cast bullets at Clements Custom Guns. The groups shrank from 3 inches to 1.2 inches using the same size .452 bullet. Rugers have tight cylinder mouths....449-.448 inches. The bullet gets squeezed down then has to ride loosely in a .451 inch bore...NOT GOOD! Get a dial caliper and measure your cylinder throats to decide what size bullet to use. Smiths are usually dead dead on at .451. Cast bullets should be sized .001 inch over throat diameter. Comparing 38/357 dies and 44Sp/44 Mag dies is not the same, they are MADE for the longer length! I load commercially on a Dillion Super 1050 (7 of them!) and we have 2 different machines for 45 ACP and 45 Colt! By the way, I load 3000-5000 rounds a DAY! 6 days a week! Election years are always the best for business!

In a survival situation, I could make it work, but it would be foolish to try it otherwise. If cost is a factor, then buy a set of Lee dies for 25$. If you watch the sales, you can sometimes get them for under 20$.

my suggestion is with as cheap as a set of dies are, why bother! why not just buy the correct dies and be done, then you know they will work properly and safely. when you go about trying to do things not intended for their purpose, is when accidents start happening. reloading ammo is not an area for taking shortcuts when the proper equipment is available.
