azmark, Here's one of My 357 Blackhawks. This one is a 357/9mm Convertable (BN-34X). With the 9mm cylinder installed and the best loads I can find .... it shoots paterns not groups. However, with the 357 Mag cylinder installed, it shoots very nice groups using the same ammo I load for all my other 357s. I actually shoot my old Liberty 6.5" BH (BN-36) a little better off hand but from a bench rest, there's hardly any difference.
Shoots like a dream. The .357 is the least problematic of all Ruger's single actions. I've had several and they all shoot great. Just remember the short barrels are not going to group MOA, but are sure a 'hoot to shoot"!
all things equal a short barrel will shoot just as accurate as a long barrel. they are just harder to hold. because of the shorter sight radius.takes a lot more practice. which is good. the short barrel packs much better.
On a good day I can hold 2", 2-hands, unsupported. That's about as good as I can shoot any of my guns, tho the single-action is more hold-sensitive to me. I'm also impatient and vary my grip a bit, which helps not at all. Find your comfort spot and be consistent.
I have a .357/9mm convertible. I've done 2" groups at 15 yards with .38 special and the revolver should do better. As Iowegan said, there is a bit more scatter with 9mm. I'm glad the one I bought was one of the "old" ones with rosewood grips. I don't like the new rubber grips nearly as much.
I'm trying to figure out a handload that works best. Haven't decided yet, but that's the fun of handloading and shooting.
I have a pair of 50th .357s, one shoots great, the other shoots scary great. From the bench at 25yds. it will shoot from just under an inch to just over an inch with loads it likes when I hold my mouth just right.
I haven't shot my convertable for group but just plinking with both cylinders the gun is great!!
The 357 is easier to shoot than my N frames and the 9mm is just great fun and cheap to shoot.
Reloading the 357 can really make the 357 sing. I load some 180 grn jhp's and am ordering some 190 grain lead to see what they will do!
