Re: Trim 454 cases for 45 colt?
I've never dimensioned one, so don't know if this is true or not. But I've read -
When Mr. Casull dreamed up his round, he knew he would have to make it longer, so people could not load them into 45 Colt guns and blow them up.
But the 45 Colt powder capacity was already so large that making the case longer, and therefore the capacity greater, was not a great idea.
So where the length was added was the web. Let's say the thickness of a standard 45 Colt web is (I'm making up numbers, now) .125", the thickness of a Casull web is .225". That's where the extra tenth of an inch went. That's why they use a rifle primer - the thicker web means a longer flash hole, and the hotter rifle primer flame makes it through to the powder better.
If this is true, and the internal capacity is the same for both Colt and Casull, then trimming a Casull to Colt case length will mean less case capacity, and if you use your normal load it will be over-pressure. You would have to come up with different loads for these cases. On top of that, all these are small rifle primed, while all your other 45 Colt brass is Large Pistol primed.
Just seems like a mess, to me, for what - 35 cases (you said "box and a half" and they come in either 20 or 25 boxes, depending on the maker)?
I'd agree that little isn't worth messing with for selling. I'd either give 'em away or throw 'em away, before I went to the hassle of trimming them down.
