Same? 45 Colt vs 454 Casull in '92 Puma?

    Okay, I KNOW the cartridges aren't the same.

    What I'm wondering is whether the Rossi (as they were, before being sold) 92 Puma in .45 Colt has ANY mechanical differences for the .454 Casull other than the length of the chamber.

    Why? I reload 45 Colt for my Ruger, my Contender, and my .45 Colt Puma.

    IF there are no mechanical differences between the 45 Colt and 454 Casull other than the chamber itself, I might infer that loads developed for Ruger and T/C would be safe in the 92 Puma. If the Puma can handle the 454 Casull by just lengthening the chamber, and dealing with the pressures generated by the Casull :what: cartridge, it should be pretty stout.

    So - does anybody know if the Casull version has anything else to add strength?

    I DON'T load 45 Colt for anything but those three - so I'm not out to wreck an old original Peacemaker with it...

    Thanks!

    Hmmm, I too would like to know, but my guess is no, there's nothin special about the .454, so I'd think your stout loads are safe.

    Having said that, there IS a difference (not relating to strength), other than the chamber length, and that is the action bar length.

    Not sure if you've seen this article from Paco Kelly, but it doesn't sound like he thinks it can handle a lot of really stout loads.

    My dad has loaded some pretty stout loads in his Ruger revolvers and his Navy Arms (Rossi) M92 lever action with no problems. I don't remember the exact load specs but it was something like 18-20g of little gun with a 300g HP that generated like 1200 fps in a 5" revolver and 1400 fps in the 20" rifle. No signs of over pressure and .44 magnum type performance makes it a nice performing round with a skilled handloader and the proper firearms.

    I believe they have the same receiver. On the 454 rifles the mag tube is threaded and screws into the receiver to keep it from walking under recoil. The 357mag, 44mag & 45Colt Rossi round barrel rifles aren't threaded and some have problems with the mag tube walking forward when firing some really hot loads.

    I just bought the 20" octagonal barrel 45 Colt Puma '92. I've been looking for information on the net for loads and it appears to me that the general consensus is that the 92 will handle anything listed for the Blackhawk and T/C. I plan on running mostly cowboy loads, but I'm going to load some longshot in the stouter loads under some 250 gr lead. Not looking for screamers, just a good thump.

    Right - I'm not trying to make a .454 Casull out of my Puma. Thing is, though, I would believe it's reasonable to infer that the differences relative to strength of the action itself on the two carbines are minimal to none, at least from the perspective of using loads that are marked "For Ruger and Contender Only." As said - those loads are enough for a healthy "thump."

    I don't have any interest in pushing my luck too far; I'm just looking to see if there's any evidence to the contrary that the Puma should be considered capable of anything you'd put in your New Model Blackhawk. So far, I haven't found anything contrary. I hadn't thought of it when I first asked, but I'd think too, that if that action is up to handling .44 Mag loads, the question of action safety margin is already answered.

    The Paco Kelly article - duly noted - about constant use of high performance ammo - I'm one of those guys that likes the Cowboy Action stuff at the range, but still like to take the rifle hunting now and then, so we're talking under 50 rounds a year of the heavy stuff.

    Thanks for your thoughts, guys! I do appreciate your sharing.

    Know what - I just remembered that I heard an allegation while back that said the .454s receivers were heat-treated in a different way to make them stronger - so you may want to hold up until you confirm or deny that allegation.

    Thanks, Doc!

    Good of you to post the article contents.

    I checked my Lyman Pistol & Revolver 2nd Edition Reloading Handbook, and found a load in particular that I was interested in - a Keith 255gr SWC - in the "Ruger and Contender Only" section. I used QuickLoad to calculate the pressure on their recommended max load, and the pressure of the "Hot" load for the Ruger & Contender works out to pressure of 22,601, way, WAY lower than the loads in the article.

    For my purposes, that's quite enough. As the article indicates, the little carbines with hard buttplates and hot loads DO recoil, enough to make you want to use your Cowboy Action ammo for casual shooting and hold the hot stuff in reserve.

    Thanks for posting the article. I had copied it into my reloading data folder for the .45 Colt. I have some Longshot and some 2400 which I plan to use under some new 255 gr LRN from a local caster. I doubt that I'll ever get over 30,000 with my arthritic shoulder, and only a few at that pressure for deer hunting. I already have seven "better" guns for big game!

    I was at the range yesterday. Shot about 150 200 gr Laser Cast over 11 gr of HS-6. This was a pistol load from a few years ago. It was a bit stouter than the Trail Boss loads. Used it for a couple tables of bowling pins at the match. Man they were flying! I drifted the rear sight a bit to get it centered. Still shoots a bit high around 25-35 yards at the lowest setting. Will be shooting it at 50-100 yards next time I'm at the rifle range.

    Got a lot of interest in the new gun. A couple of the experienced hands shot a few rounds and pronounced it a keeper. The action is slicking up real nice.
