Reloading pressures

Sometimes its best to just ignore the "good idea " fairy!

Jolly good idea

Or just aim a foot high at 100m with you old acp?

Thanks for that Blu, I have some Federal 45 Auto brass here which is .012" so a similar thickness .308 brass is considerably thicker at .022" when trimmed to .898 in (22.8 mm) so is it going to fit the chamber?

I think Dromia there said it best.

Agreed, an interesting exercise all the same and I do wonder how people do actually use .308 brass. The only thing I thought of was neck turning the outside by a set length, then expand and seat the bullet and when fire formed it would leave a register on the inside to seat the bullet up against as per the Bench Rest shooters many years ago, the only thing is they did this to make reloading a lot quicker in the field and is that really needed for a .45ACP rifle?

Interesting all the same :cheers:

Dave, I just tried cutting down two .308 cases to the same size as a .45 Auto case. Both cases after being cleaned up ran through the FL sizing die no problem. The problem started when I tried to flare the case mouth. It had to be forced and then all it did was crush the case because the thickness of the case. The second shell I didn't bother trying to flare the mouth of the case, just cleaned it up and tried chambering it in two different 45 Auto pistols. Again because of the case thickness the shell would not chamber on either pistol.

Thanks Blu you have confirmed my suspicions, it could be the basis of a wildcat though but you just know it will have been done before and probably with a 30-06 back in the 1920's :lol:

There are various wildcats developed from necking down the 45 ACP. The .451 Detonics is the first wildcat I know of that involved a strengthened case from this, the 45 Super was developed.

The Detonics was a shortened 45 Win Magnum which, in turn, came out just after the 44 Auto Mag was announced - which as Saddler said is simply a shortened 308 (or 30-06) case.
