got both the 77/357 & 77/44 stainless guns a few years ago, and i like them pretty well.
after a few scope changes, i found the Leupold 1-4x works well for me on both of them.
i havent shot the 77/44 as much, but have tried quite a few different powder/bullet combinations in the .357; mine prefers bullets in the 125/140/150 weight class.
158's and heavier have not shot as well in my rifle; with 158/160/170/180's & several assorted powders i have tested , groups were considerably larger. i tried a bunch thinking i'd stumble on a magic combo it liked, hasnt happened yet.
heaviest bullet i could make it like was the Sierra 150JHC, still have a couple hundred of those.
