.45 ACP same as .45 LC?
I'm working on getting all components together to begin reloading, but yet to get a reloading manual. A quick question is, the .45 auto projectile (bullet) the same dimensionally as the .45 colt projectile? I realize there are different weights depending on style and application.
Thanks, Nunya |

A manual should've been your first purchase. It will answer alot of your questions now and in the future. I suggest you buy a couple of manuals and read them from cover to cover.

You MUST have the book(s)
But in the meanwhile, the correct answer is "almost." .45 ACP jacketed bullet diameter is commonly .451", some .452"; .45 Colt is nearly all .452". .45 ACP cast bullet diameter is commonly .452", .45 Colt runs from .452" to .454"+. Some loaders use 230 gr roundnose .45 ACP bullets in .45 Colt satisfactorily, some have trouble with the thousandth undersize, short bearing surface, and lack of a crimp groove. The 200 gr roundnose flatpoint sold for Cowboy shooters to load in both .45 Colt revolvers and carbines often works quite well in an automatic. There are a lot of other shapes that won't. |

Before WW II .45 LCs were sized at .454. If you're loading for an older Colt, of undetermined vintage, then measuring the barrel is advised. Otherwise, .452 sizing works for .45 LC and .45 ACP as well as many other Cal .45 cartridges.

45 caliber rifle uses a totally different bullet. They are sized to .458 which is different from pistol bullets. All 45 caliber is not the same. Thought you might want to know.

Bullets for 45 ACP and 45 Colt are generally the same overall diameter, but those designed for 45 Colt have a cannelure (crimp groove) to accommodate the roll crimp commonly used for that cartridge. Bullets designed for the taper crimped 45 ACP do not have a cannelure.
So while you can use either one for 45 ACP, using 45 ACP bullets for 45 colt means you would need to taper crimp instead of roll crimping. Andy |
