When loading heavy .357 slugs for lever guns, you must pay attention to the over all loaded length. And, you need to pay more attention to what your rifle says than what the books or websites say about the length.
The heavy .357 bullets are long, relatively speaking and what works ok in a revolver cylinder MIGHT not work ok feeding from a carbine's magazine tube on to the lifter(carrier) and into the chamber.
Long ago, friend of mine gave me a box of 210gr LRN .38 bullets. He had gotten them to use in his Marlin carbine. I no longer recall what they measured (or even if I did measure them) loaded "to the groove", but they look long. He loaded I think 5 rounds, then "got smart" and decided to test them through the action before loading up the rest.
He put 2 rounds in the tube and worked the action. It froze, and he brought me the rifle to help him take it apart. I did, got the ammo out, and put it back together, the gun was fine, but those rounds were too long to feed. So he gave me the slugs he hadn't loaded. They'll work single loaded into the chamber, they worked in revolvers and in my T/C single shot, but not from the lever guns magazine.
SO, when you get some 180 cast stuff, I would recommend you only buy the minimum amount and do some loading and testing to see if they're ok for your gun and what you want to use them for, and IF they are, then buy in quantity. They aren't all the same, and different rifles can be different about what they'll run and what they won't. Marlin .357s (in my experience) are picky. I don't know about Winchesters (or copies of Win designs), never had one.
Good Luck! Hope you find what you want.
