Regarding .454 Casull FACTORY ammunition and stainless steel (only) M1892 replica rifles chambered for it:

1. Factory ammunition is almost certainly loaded for use in handguns rather than rifles. What changes in muzzle velocities should I expect from 20-inch barrel, from 24-inch barrel? I ask because I expect there is a break point where longer barrel yields LOWER velocity rather than slightly higher.

2. Please identify M1892 replica .454 Casull rifles that are available in stainless steel. Are these rifles' actions entirely stainless steel except for springs, or are there but a few stainless components with most action parts non-stainless?

3. Has anyone tried to install XS Systems Ghostring sight system on the rifle? If yes, what results?

4. There is an enormous difference in back thrust on M1892 breech bolts in .454s compare with ANY other chambering offered by any manufacturer. Is heat treat or stainless steel used different, or is headspace caused by breech bolt compression something to monitor?

5. Among the importers/distributors for these rifles, which specific one has the best parts inventory and repair facility? These may not be one company, though.

6. Has anyone fired more than 1000 FACTORY .454s through a stainless steel M1892 replica? If yes, now how's it working?

I think that the guy who ones buffalo bore or corbon ran over 1000 of their ammo. I cant really remember where i found that out though.

You are right that as the barrel gets longer you reach the point of diminishing returns and after that increasing barrel length decreases velocity. How ever in any practical rifle barrel length this effect occurs only with the 22 rimfires.

With a 454 you will still be gaining velocity. The rifle will produce more velocity than a handgun, but not a tremendous amount more as it is after all a handgun cartridge. The real velocity loss will come after it leaves the muzzle. From a carbine barrel the 30-30 or the 44 mag will both out perform the 454 at any range over 100 yards with less recoil.

Unspellable , I respectfully disagree ,with you statement ,the 454 will out perform both the 30/30 & 44 mag. @ 100yd.s ,, easily.( when all have same barrel length.)

I respecfuly agree with Buckeye. A quick glance at a reload manual shows the 454 as much as 500 f.p.s. faster than the 44 for the same bullet weight . That is the extreme spread. I do not know how to crunch the numbers in regards to the 44s B/C advantage but it seems like a lot to over come in sheer velocity. I reload and shoot all three rounds and would rank the 454 close to the 444 marlin, and 9 rounds of 454 power is a lot out of any gun.

When it come to choices for the 454 in a #92 I think there is only one choice. Legacy/Puma. Again I think we are only talking about a 20 inch barrel. Mine is in the blue and I have only seen the stainless in the Legacy flyer that came with the gun. My gun still has a low count on rounds fired and works fine so far. On one of these message boards there was a fellow that had a problem with his Puma and it sound as though he had a very good experience with the repair that Legacy did.
