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 !
