sullkat,
Like I said, the .357 is the most difficult of them all. Don't ask me why, but the guides are made and set to supposedly feed cartridge lengths from the .357 Mag to the .38Spl. With the myriad nose styles and bullets weights to be found... the attempt to do all things, sometimes translates into doing none well.
Like I said, they are fixable. Takes a little know-how, and some sweat equity.
As Griff said the most troublesome are the 38/357 guns. That's usually because there are so many different brands and shapes and OAL`s of 38`s and 357m’s out there it’s impossible for one gun to cover them all. All our leverguns are length and bullet shape sensitive to some degree. Like semi-auto handguns, they can be picky about what they will run.
Generally, they don’t work well with really long 357’s or really short 38’s. Bullet shape can have a bearing too. Ususally they don’t work well with semi-wad cutters or any bullet that has an exposed driving band to hang up on. Again, much like a semi auto pistol.
But, in your case if the new win will run it but the rossi won't then you may have a bad gun. You already know they will work because you said you have two Rossi's in 45lc. I guess what I'm saying is don't make a general assessment of the all the 357m guns from just a single sample of each brand.
My experience comes from 20+ years of working the 92's. Here is a few things that I've found. I believe the finest 92 ever made was the B92 made for Browning by Miruko of Japan. It's as close to the ordinal design as possible and is made with modern steel. No tang safety, no lever activated trigger block, no stiff to cock rebounding hammer, no spring loaded 5 piece firing pin. But sadly it is no longer available and they only made 20" all blue carbines in 357m and 44mag. Production stopped in the late 80’s.
But, even the B92 guns had problems. I don't think the cart guides are correct and some had 1 in 40" twist and just didn't shoot worth a hoot. I recently rebored one to 45lc becuase the owner just couldn't get it to shoot.
Rossi has always been 1 in 30". Some folks think even that's too slow but I feel they are confusing pistol twist with rifle twist. The 1 in 30" works well with the faster rifle velocities.
Now, lets talk about what I've found with the lawyered up Win Mirukos. Early on the guns were prone to stove pipe. This is because the carrier detents were just setup wrong. The latest ones seem to be better. Then some folks have had inconsistent ignition problems with the Win Miruko with it's rebounding hammer and 5 piece inertia firing pin. Next, they have always had the wrong cartridge guide configuration. The Win, the B92 and the Chiappa ArmiSport all have cartridge guides setup to work best with bottleneck carts like the originals. The problem with that is most are chambered for straight wall carts. The Rossi cart guides are setup for straight wall. If they weren't Rossi wouldn't have been able to chamber these guns in 454 Casull.
You have to take in to account that about 30 to 40% of the cost to build a gun usually goes toward the final fit and finish. What that means is just because it looks well fitted and finished that doesn't guaranty it will work right.
Think about this. All the folks that made the original 92's are long dead and gone. The folks with the most experience building 92's now are the Rossi folks. They have been doing it for 30 something years. They aren't finished as nice as the others but they don't cost twice as much either and functionally it's closer to the original than the others so the dang things work. The cartidge guides are setup to run straight wall ammo so they are not as ammo sensitive. They don't have all those tiny add-on parts to fail and if you want it to run smoother they aren't that hard to work on.
