Well Mr. Chill Wills . . . Just kidding . . .

I document it by shooting ammo that can be tolerated by the open-top platform that a particular top strap can't handle. Such as firing...

The top strap Remington in fact isn't the stronger design when the open-top is built correctly, as in Colt instead of "Italian" reverse engineering ( short arbors). The top strap is a "perimeter" ...

Pressure data doesn't include bc gap. That varies from revolver to revolver. Chamber pressure is CHAMBER pressure. The bullet moving forward is the pressure "relief" until the gap is crossed and...

My 2 favorite 45acp revolvers are my Uberti '60 Army's with Walt Kirst's cylinders!! They are both very accurate and +p ammo seems to be the preferred ammo. Definitely correct the "short arbor" with...

One would definitely pay more if "they" did it. These days Uberti is the only game for pocket pistols so . . . You can shoot um and put up with um, fix um yourself and have an excellent revolver...

Many times the recoil ring needs to be relieved on the outer edge. The ring is a little large in diameter and when caps are installed they can contact the edge of the ring. That's why it'll function...

If they're broached after the fact . . . absolutely.

Nope, don't see how they would know to make yours correct and ALL the rest wrong. I'm pretty sure yours don't have a "witness mark" at the bottom of the arbor hole indicating contact with the arbor....

That doesn't work without dressing the arbor since they only go together with correct orientation. Why would you make a too short arbor too skinny as well . . . just to test for what you already...

I'll check my Pietta when I get home. I know the Uberti's are good, I shoot jacketed 230 and 250grs bullets.
My thing about the Pietta's anyway is the slow twist . . .
I'd think Walt would...

Well I can see some of you folks are Pietta fans. Even though their arbors are (for the most part) correct, they're a little on the "generous " side for endshake . . . but that's easy to take care...

TD1886, is this a new Pietta?

BTW, all mine are Uberti's. I've had a Pietta set up with 45C but my Dragoons were the first.
I recently made a trade with Walt and ended up with a Pietta again (...

Well, I don't know what you measured with but the Pietta and Uberti barrels are .452" and either will handle 45C / 45acp bullets just fine. In fact, that's all I shoot in my '60's, Dragoons and...

Well there ya go!! Ask a rhetorical question, get a "serious" answer!!!!

It would help to READ the posts for even a little context before posting an "obvious" statement.

Ruger's instructions say to use only "commercial" ammo made for the caliber the revolver is chambered for.
So, what's a "Ruger only" load . . . ?

Mike

Hey LIMPINGJ, like has already been pointed out, they are both 6 shot cylinders ( Howell and Kirst). The main difference between the 2 is the support each has for the case. The Howell has a...

Yes, what Doug says!

Brian lists the revolvers that shouldn't be used. This info is in the current issue of Handloader Magazine. The load I provided is a less than full 45C+p .

Nice for single action revolvers though!!
Thanks!!

Mike

Oh yes, it will get your attention for sure!!

Mike

The most destructive "feature" of a single action is the endshake spec. Shooting heavy loads and heavy bullets does exactly the same thing that loose cylinders on open-top revolvers do. The cylinder...

You know there is a "range" of "Ruger only" loads? It's not just "a" load. As I posted above, I shoot lower end "RO" loads in open-top platform revolvers with conversion cylinders. I wouldn't...

Well, mine is a fixed firing pin, 4 click hammer. I added a 45acp cylinder to it. It had other issues when I got it but it's all been updated/fixed now. Runs like a fool. Wouldn't go out of my way...

Yap, Brian Pearce is probably the best source with documentation and equipment for such. He states the Uberti copies are suitable for 45C +p loads. I've been testing the Uberti open-top platforms ...

Except for my Pietta made 2020 Cimarron Frontier.
