Be gentle to your Berretta. If you want hotter loads use a Ruger, even better a Freedom Arms model 97, or best Buy a bigger gun. There are plenty of really nice 454 Casulls, 480 Rugers and 500 Smith and Wessons. If you want a gun to shoot like a 454 Casull Buy one, enjoy the Single Action Army for what it is.......DJ

DJ - Thanks, but you can have all of my .454's, and .500 S&W's. I do have a Ruger Blackhawk .45 Colt that is all the steam I want for now. I'll just keep my Ruger loads away from Beretta, as you suggest. The Freedom's Arm pistol does interest me or maybe a Gary Reeder's "make-over" of my Ruger. Regards - Riley

The Seville was made by US sporting Arms for awhile, but they ran into patent problems with Ruger and went out of business. You can find them used sometimes. I have a 45 Sherrif's model and a Stainless 357 max. They are both really nice quality guns.
If you have a Blackhawk already, then maybe an option would be to have a 44 Bisley cylinder rechamber to 45 colt with tight chambers and correct throat. I don't know what they would charge for that?
I was thinking of getting a 480 5 shot cylinder and converting one of my Blackhawks, but at $350 for the cylinder Plus the gun, and even if I did all the rest of the work, I could just as easily buy a BFR in 475.

Actually, the FA Model 97 is chambered for .41 Mag in a five shot cylinder. I do know it is no Model 83, but I've not heard that the Ruger is a stronger revolver.

The prudent reloader will note the thinner cylinder walls of the M97 (see post above) and make the right decision*. Heck, Elmer used to load SAAs until he blew the top straps off - there's no accounting for some people's ideas on personal safety.

*John Taffin won't use top Ruger loads in his M97....

I own a Ruger SS Bisley Blackhawk in .45colt and a FA 97 in .45colt. And shoot them both.

FA97: My hunting load will consist of an Oregon Trail 255swc hard cast at velocities of 1000fps or less. Not because of pressure concerns; but because that is all that is needed to take anygame I choose to in my neck of the woods (deer)
Read sixgunner.com or sixguns.com if you need more info.
Buffalo Bore load for the FA 97 appears to be quite spirited. What is it; 300gr @1200fps? Correct me if I am wrong, but this presentation was created due to the shorter cylinder length of the FA97. I will try some this spring to see how well my FA likes it.

Ruger: Tuff. It has handled everything that I have put through it with no problems or concerns (factory ammo). This revolver has alot of mass for good reason.

I am still at level one on the knowledge pole, but the more I shoot, read and shoot again, the more I like what this caliber has to offer.
