I showed my new to me Rossi Carbine in 357 mag to a friend. He suggested I get it rechambered to .357 Maximum if I was to use it for a hunting backup gun.
Anyhow, I got to thinking if that was even possible with the action length, rails etc. I doubt I would do it, as my 357 reloads are quite stout and only for quick close shots that are too close for a scope. But, if it was easy, I might consider it.
Possible? Stupid? Let me know.
Cheers
 
My guess would be no, the increased OAL wouldn't feed properly. But that's purely a guess, I'm not very well versed in lever actions. I look forward to hearing from someone more knowledgeable than I.

Looking at pictures I'm not sure the round would even clear the magazine tube when it was on the lifter? The OAL is like 10mm longer than 357mag/44mag/45lc.
 
I have a 92 in .44 mag I'd trade for a .357 That would get you a little extra stopping power (and it's the only thing I have in .44 mag!).

Why not go to 45 LC? Stopping power is an illusive concept... some folks say it doesn't exist.
Other folks go with big and heavy...hence the 455 out stopping the 45 ACP at whacking pigs around turn of the century during testing.
Had a 44 magnum in a Rossi Mares leg. Would gladly snap one up in 45 LC to fill the void.
I think 357 Max was a great idea on paper... just never took off for some reason.
 
T'aint no way to get the 357 max to function in the 92's as it be too long, but it would be easy in a Winchester 94.

I be more than satisfied with my Rossi RH in 45 Colt. I sold the one I did up in 357 mag along with a 16" barreled trapper in 44 mag, only because I'm
super fond of .45 bore rifles.;)

At that point, why not just use the 30-30 though? Use the same weight bullets at higher velocities and with better sectional densities.


That said, they make 92s in 454 casull don't they? Are those the same size action or are they special? That's a longer cartridge than the others?

The Casull is a 'Rioded out' 45LC is it not? Be interesting to see a 45 LC Mare's leg alongside the 454 in a 92. Wonder how similar the reciever's would turn out to be?
Might be able to run some pretty hot 45 LC if they were the same...

Why is a backup gun required? Backing up what?

My scoped rifle just doesnt fit all situations. Sometimes a quick, open sighted rifle is better. I saw a crap load of bears last fall, plus one that actually was only 10 ft from our camp one night. I only saw him when I stepped away to pee. My scoped gun is useless there in the dark. Also, came around a tight bend in a river and nearly hit a moose. I shot him at 10 yds with the "backup gun" (model 94 .30-30) sitting in the front of the boat for anyone to use. Some guys mean backup gun in that they may have a gun malfunction and have a second gun there to replace it. I just mean another gun with open sights for close range.
 
A handgun of sufficient caliber in 357,44,45C on your person w/ operator proficiency will serve you better than an open sight carbine leaning against a tree or stashed out of reach when needed.

Dual tasking would be possible...while relieving one's self...with the handgun.

That would be great if we were allowed to carry handguns but.... as this is Canada that is nothing but a dream.

I see you are in Fairbanks. No handguns here unless you bribe someone to issue a Wildness Carry Permit. Other than that...non-obtainium.
 
Probably better off going to a 357/44 or 45. Maybe a 357/454 as Rossi already makes a gun in 454. But the overall length makes a 357 max not possible. With all that said. You’d maybe 35 Remington performance. It kinda brings up the question of why. You can buy any beater 32ws 38-55 or 30-30 and have it cut down to 18.6” for less money than rechambering a 357 mag and getting it to feed. Or be patient and go blr in a wsm or 450 marlin
 
Not really thinking about changing my setup. I use either a .375 Ruger Alaskan or my Win extreme weather mod 70 in .30-06 as my primary rifle while big game hunting, but always have an open sighted rifle on hand for up close and personal chances. I am quite happy with my little Rossi M92 in .357
I was just curious if it was possible for a rechamber as a friend mentioned if possible. Up until now, my open sighted backup was usually a shotgun, but this 16" Rossi is so nice, slick, and handy, that it got promoted. I also am not worried if I have to use it at close range. My loads are probably only 10-15% less than a 30-30

Yupp. From what I hear unless your need is work related they won't issue it. Hunting, hiking, or camping in Grizzly country? Too damn bad!

10-15% less than a 30-30? What are you using for a load then?

20" barrel. I believe they use 24" test barrels for those factory numbers. It is still very cold here, so my chrono could have been reading a bit slow.

That wouldn't surprise me. Nosler's load data specifically states they used a 20" barrel, and their 150gr loads are 2146-2270fps (for max loads, depending on powder) so 2070 still sounds a bit on the slow side though. 2070fps doesn't sound like a bad load for a 170gr bullet, but I don't think I'd be happy with that velocity for a 150 (but I'm a velocity whore.)

https://load-data.nosler.com/load-data/30-30-winchester/

It would be interesting to compare that load with factory ammo, see if its the load or the rifle giving you such low velocity.
