I was wondering if anyone has cut down 30-06 brass to make .45acp? I believe the 30-06 was the parent case for the .45acp. Is it just a matter of the overall length or is there some other difference in the two cases? If 06's can be cut down what would be suitable for this( besides a lathe)? I have hundreds of 30-06 and 25-06 brass that came with my reloading gear, and wouldn't mind trying to make some 45's from them. I was thinking maybe cutting them to a rough length with something like a dremmel then just finishing them on my case trimmer and chamfering the ends. Any thoughts? Besides time involved !

It can and has been done, I believe, to create a much stronger case for high power loads. It is not enough to simply trim cases to length as the case walls of the 30-06 case at .45 ACP length are much thicker and require reaming in order to seat bullets.

Section a 30-06 and a .45 ACP case to see how much work is required.

Once trimmed to length the cases have to be reamed out to .452. This is how we make .45-08 cases but we use .308 cases for teh cartridge, hence the name. A lot of work just for .45acp cases.

I've cut down rifle brass (.243, .270, .308, .30/06) for use in a .45 acp pistol just to see if it would work in an emergency, and found it is not worth the effort. The inside diameter of the rifle cartridge case is .44 caliber, so the case must be reamed to accept a .451" bullet. The rifle cartridge case is not beveled ahead of the rim, as is the pistol case, and the result is that it is very hard on the pistol's extractor. Loads that are appropriate with the pistol brass will prove much hotter when loaded in rifle brass due to the thicker web and reduced capacity of this brass. When combined with the non-bevelled case, these hot loads will probably cause a good unmodified 1911 pistol to fail in short order.
