Cylinder ball problem

    Ok guys I need some help on the right size ball to use. On my 62 colt police by uberti. I'm using .375 balls and after I seat the ball firmly on the powder they creep alot in the cylinder. Actually once I seated the balls one just fell out of the cylinder. There is a tiny bit of lead shaved just on one side of the chamber. Will .380 balls fix this or do I need a new cylinder?

    It's fairly well known that most of the Uberti .36's need .380 balls.
    It's the Pietta's that use the .375's.
    That does make the Uberti's a little more problematic to buy ammo for.

    Are you buying the balls or casting??

    I bought them. There hornady .375 where's a good place to buy .380 balls? I'm not in the whole casting process yet.

    well, that explains why even hollow based .38's aren't all that accurate in my Kirst converted Uberti Remington.

    Actually the bore size on both the Pietta and Uberti .36s made in the past 10 years is very similar (.375-.377) But most of the Piettas have chamber sizes of .367 to .372. The chambers on Uberti .36s I have measured over the past few years are closer to bore size (.374-.376"), even a tiny bit over depending on the gun. If you want good accuracy from a cap & ball revolver, it is more likely if the chamber is slightly larger than groove diameter and you load a ball that is .004-.006" larger than the chamber size. .380 round balls will give better accuracy in most .36 revolvers regardless as well as help to prevent chain-fires.

    .380s if you can find them are your best bet, as stated above.

    An alternative when it is available is 0000 buckshot, which mikes .380 to .382:


    Buckshot is not pure lead so it takes a bit more pressure to seat in the chamber, but I have used it for years in my 1851s using just the rammer on the gun. I do not remove the cylinders for loading. And the price is attractive...you get close to 800 balls for about $40.

    or you can put a watch for .385 mold on evil-bay , I won't feed my 36's anything else.

    Preciate the help guys! I'll order up some .380 balls today. I know the sprue goes up, but does it hurt accuracy any?

    LEE sells a nice 2 cavity .380 mold. For not too frequent shooting it will serve you for many years. For serious shooting you can either get a 6 cavity .380 gang mold from biglube.com (around $80) or from buckshotmold.com a 0000 buckshot mold (around $40) that will throw 10 balls at once. No sprue cutter on that one but cast very economical balls that have a slight flat diameter ring on them but for most plinking and CAS matches they are plenty good ammo.

    My ASM's chambers are .374 and obviously doesn't shave a ring with .375s. The .380s (TOTW) shave a nice ring.

    http://gadcustomcartridges.com/ - These fellas charge $6 per 100.

    How about the .44's...Uberti vs Pietta? Size difference needed?
  15. swathdiver

    My latest Pietta's have .448 chambers so .454 balls would be undersized. Ideally, the chambers should be .452 and use .457s for best accuracy.

    I'm not sure if I follow...
    .454 - .448 = .006" how does that make yours undersized? (the chamber is .006" smaller than the ball)
  17. swathdiver

    When you squish that .454 into a .448 chamber it becomes a .448 ball. Then you pull the trigger and that .448 ball goes through a .451 barrel...

    Reaming the chambers out to .450 will increase accuracy and you can still use .454 balls.
