Dave,
IS .409 the only rd ball you use? I shoot way to many different cals. and The way I work is.
I will use the .490 for a while then switch to the .454 hollow point for my ruger, then do some .365 for the colt navy.By that time the .490 is cool enought
Yes, I have two .50 caliber rifles and one mold - so far.

Look at it this way. With the single mold you know it casts the same size. I have a Lee 54 cal single cavity. I know it takes time but its uniform. I have a double cavity Lee mold and there is a very slight diffrence in size between the two. I doubt if it makes a diffrence, at least the shooting I do.
Good point on consistency. I'm mostly a plinker at this stage, so I doubt if a bit of variation would matter too much. As it is, 700 balls will last me quite a while. I will check and see what Cannon Mike has to offer.
