45Lc Rugar loads

[Tucson Bill]

While researching loads for the Rugar 45LC ( Linebaugh & Hawks ) it was stated not to go above 29,000 cup as the 45LC case was the limit. Has anyone used a 454 Casull case cut to 45LC length? This case uses a small rifle primer and may/should be stronger.

The .45 Colt / Large primer case is not the limit.
Cylinder wall thickness is always the limit on any revolver.

Revolvers do not blow cases at 29,000 PSI as they are fully supported in the chamber.

Large primers are used in centerfire rifle calibers at twice that pressure with no problems.

If you want a .454 Casull, you should probably trade the Ruger .45 for a .454 Casull.

If you want to load them heavy, Taffin Test is the place for data. A lot of 45 Colt testing was done by miking the case head diameter and watching for expansion. With todays electronic pressure metering those days should be behind us. Like RC said, don't try to make the gun go beyond it's limitations.

Sorry to correct you RC but he said CUP pressure which differs from PSI.



OP. It is not the brass case that is weak on the 45 Colt, as it is said to be, but more so the cylinder on the gun. All the brass really does is seal the "chamber". once it is sealed the only unsupported portion of the brass is at the thinner part of the webbing, where a looser revolver may let the brass protrude out the back of the cylinder a bit. but it takes more than any .45 Colt chamber or cylinder can handle to rupture this on good brand new brass without a "bubble" type head. Starline .45 Colt brass can handle .44mag pressures which is way higher than needed for anything out of a .45 Colt firearm. The .454 Casull is running a higher pressure than a .308 Winchester rifle case and this is almost a classification within its self. More like a .454 Casull is a rifle round in a pistol frame.

I know the difference between CUP and PSI.
In this case, it simply doesn't matter.

And I'm pretty sure I said the cylinder, not the case was the weakest link.

So what are you sorry you are correcting me for again?

I use good brass in good firearms, Ruger and Rossi "Puma", both of which can be had in 454 Casull. Published loads are safe and powerful to the point they become unpleasant to shoot in quantity. They run at about( according to factory data) around 80% of 44 mag pressures and in some cases well exceed 44 power production.

I certainly have exceeded 29000CUP in my Blackhawk. There isn't much need to though. That's a hell of a powerful load that will kill anything that needs killing with it.

The head of the case for .454 Casull is beefed up quite a bit, but I have yet to the 45LC revolver that can handle more pressure than the 45LC case can handle. There were published caustions about trying to do .454 Casull pressure loads in the weaker .45LC cases, for 454 Casull revolvers, but as long you are keeping pressures down to Ruger only 45LC loads, standard 45LC cases are fine.

the PSI statement when he clearly said CUP. It can matter to someone on the ragged edge of top end loading, as CUP is usually lower than PSI and we need to keep it on an even scale in this type of forum for high end loading. the second part is not specific to you, i was agreeing with you on some of it that was just second to the OP in general. It has been rewritten to be understood easier.

Thanks for your input, some good INFO to ponder!
Don't want to load to 454 pressures, just wanted to know if 454 brass would add a measure of safety.

What you are saying boarders on the nanny-state mentality. Read what's written and act accordingly. We are all adults here and have a personal responsibility for our own actions so if you read something incorrectly it's your fault, not the author. This used to be the way we acted in this country but sadly no longer.
