    .45 Colt bullets normally have a cannelure to roll the crimp into. The slick sided .45acp bullets can jump crimp and tie up a revolver if the loads are heavy enough.

    That said, you can use .45acp bullets in .45 Colt and vice-versa. You just have to be careful and think about what you're doing.

    In my case, I don't use anything lighter than 250gr in the Colt or heavier than 230gr in the acp so there is no sharing.

    Many of the Colt bullets are lead, 250, where the ACPs are jacketed, 230 tops- but there IS some crossing back of forth. Diameters usually about equal.

    The profile sometimes makes a bullet inappropriate for the Colt cartidge. While a 230 gr RN FMJ will fit in a .45 Colt, the ogive (nose radius) causes one to have to load the bullet so long that you exceed the max OAL. I use the 255 gr SWC for the Colt and 225 gr RNL for the ACP. The SWC will work in the ACP but not the other way around.

    I've had very good luck with 255 Cast GC bullets, from wheelweights, in the .45 Colt. I use the 250 gr plated Rainiers when I'm too lazy to cast.

    What? My .45 Colt revolvers couldn't care less how long the bullet is seated as long as they don't stick out the end of the cylinder.

    All .45acp bullets will work in .45 Colt revolvers (but possibly not reliably in lever guns). Some .45 Colt bullets will work in .45acp rounds.

    I'm confused?

    Are we talking about .45 Auto Colt Pistol
    or
    .45 Colt, as in Long Colt, the revolver round?

    The old, very old - I wouldn't shoot because of antique value, Colt SSA revolvers were barreled to something around .454 caliber. The modern ones fell in line with the .45 ACP bore of around .451 caliber.

    The .45 Auto has shorter over all length to fit into magazines and the chamber. Other variables must be met for proper/consistent function as an auto-loader.

    The revolver is limited by the requirement of having a short enough over all length that the cylinder will rotate. Bullet shape can go from a totally flat, even with the case mouth wad cutter to a very pointy spite shape.

    The standard bullet weight for the ACP is 230 grains and the Long Colt is 255 grains. But, those weights don't hold much weight (pun) anymore. The auto-loader must have a load that is balanced to operated the action, not hard to accomplish. The revolver just eats up anything that gets the bullet out the barrel and is safe (pressure wise) to shoot. One is fast to shoot and re-load. The other is or can be almost as fast to shoot, but far slower to load.

    You find reloaders using a broad range of .45 caliber bullet weights in both guns. You will find .45 Caliber bullets in .451,.452,.454,.457,.458 calibers.
    The .45 ACP[Automatic Colt Pistol] will most often use the .451 jacketed bullets or .452 lead bullets. The .452 in either bullet works in the ACP or .45 AR[Auto Rim]. The .457 and .458s are rifle bullets.
    The .45 Colt Ctg. in modern ammo there is no Long or Short .45 Colt ammo. The Longs and short .45 Colt Ctgs are collectors items. In modern loading most new guns are throated and chambered to use the .452 diameter bullet. Older Single Actions and some Double Action may have .454 chamber and .452 bores. These can create a problem for the hand loader. The S&W 25-5 revolvers in .45 Colt can present a problem to hand loaders. These guns will often key hole unless .454 bullets are used.
    The answer is if you don't know what bullet to use measure you chamber throat and forcing cone.:)

    You can use any 45 caliber pistol bullet. As mentioned above, the rifle bullets will be too large.

    If the bullet doesn't have a cannelure I wouldn't try pushing it too hard or the others in the gun may try to walk out.

    I think you'll find most bullets with an appropriate weight for the cartridge will have a cannelure or crimping groove.

    And if there is no cannelure, use a LEE factory crimp die,

    Locutus, So true. I was having problems with .45 Colt loads in a light revolver. I put a LEE FC die in the Dillion. Not only are the loads working without slip they look and fit very nice.:)

    I load .452 diameter bullets when I load up some .45 colts.

    If your weapon was manufactured after WW2 that is the correct diameter. Most Pre-WW2 had .454 bores. .452 bullets will work in these, but you lose accuracy and velocity.

    And if that is not bad enough? Some post war Colt SAA revolvers have .454 chambers and .452 bores.:confused:

    That's much better than the other way around. ;)

    For .45 Colt the Lee FCD doesn't crimp differently than any other pistol roll crimp die.

    You're probably thinking of the FCD for rifle cartridges. It might be used to crimp into a bullet without a cannelure, but I wouldn't advise using the Carbide FCD for that. By squeezing more of the bullet down you could actually wind up with less neck tension.
