    I picked up an S&W 58 a while back and have no idea what bullet weight its sights are regulated for. (The 58 has fixed sights.) Do you know?

    Prior to buying a bunch of bullets of your recommended weight, I mic'ed the chamber throats at 0.4115 inch. Should I search for .411 bullets or .412?

    Oh yeah, the obligatory pic: (I bought this one because it looks like a model 10 on steroids, and I already own three 10's.) :)

    My 58 shoots equally well with 210 gr. and 215 gr.

    Original factory loads were 210 grain. The most common commercial cast is 215 gr which I doubt will make much difference. That is no guarantee that the sights are right. I would not buy a bunch until I had shot a few.

    Standard bulk bullet diameters are .410" jacketed, .410" or .411" cast. Finding .412" might be a challenge.

    The throats might be .411", but just start with the standard .410" bullet and see where you wind up at.

    Actually, I'm taking my 58 out shooting next week to see what I can do with it and some new cast bullets I have.

    It does remind you of a pumped up Model 10 M&P, doesn't it? :)

    That's actually an interesting pistol you have... unlike most 58's, yours has a target hammer and trigger. Hopefully, the action matches the parts!

    My 57 action is the nicest one in the safe... the 58 is good, but nowhere near the 57.

    I cast 2 different bullets for my 41 Magnum, both SWC's. An original H&G and a custom mold from Accurate. I'll weigh and measure them tonight. If you want to try them I will gladly send you a few of each.

    I do not have a gun like that. I do have a .41 Mag. That gun is almost bound to be regulated for factory 210 jacked bullets at a pretty high velocity. Cause that is all there is. For me almost any lead bullet (actually I shoot coated) at a lower velocity is going to shoot high. I do not think you can buy lead bullets of less than 210 grains in .410 diameter. I have never found any. There is one 170 grain jacketed bullet on the market. Good caliber. Very limited offerings of bulets from commercial vendors. I tried turning some 215 bullets down to 175 grains on my little lathe. Made little difference in how they shot. Was a lot of trouble. Could find no loading data. I just aim a little lower with lead bullets now. I keep the sights set for full power loads. My best accuracy with my .41 Mag gun (a Ruger Blackhawk) has always been with full bore loads behind jacketed bullets.

    When introduced, there was still a bit of the old S&W tradition of model names and the Model 58 was indeed the ".41 Military and Police."
