    Has anyone tried loading 38 super .356 124 gr jacketed bullets for the 9mm conversion in a blackhawk?I have some .356 diameter tc and wondered if they would be any more accurate out of the blackhawk since it's a 357.I was gonna try them,but wanted to make sure it'd be safe to do it.

    I used to own the Blackhawk convertible that had the 38/357 and 9mm cylinders. The one time I used 9mm cylinder with 9mm ammo, the bullet drop was so great that I didn't have enough elevation in the rear sight to come close to the target. The shots that hit the backer board were spread out so much that I didn't measure. They definitely were not accurate. They were .356 also.

    I agree with hoghunting. I currently own a Blackhawk 4 5/8" in the 357/9mm and with the 9mm cylinder in it, it's not a very accurate handgun. Mine isn't as bad as his but still not as accurate as using 38/357 ammo. I think that it's a combitation of undersized bullets and the long jump the bullet has to make before it hits the rifling in the barrel.

    More accurate than what? Than .355 bullets? Maybe. Than .357-.358 bullets? Doubtful. The barrel's got to be big enough to accomodate the largest bullets it's going to have shoved through it, and anything undersized is likely to be a bit screwy. I expect you could load those .356 tc's in .38, or even .357 brass and make a load that's accurate enough for tin cans at 10 paces, but if you want maximum accuracy it's probably gonna be a bullet made for the .38/.357.
