440, 490, 530. Best to measure bore for best selection. 445, 495 535 for slightly over size bore.
Thegunworks.com has had good selection of moulds lately.
 
On my tc 45 and 50 it's 445 and 495. For my GM 54 drop in it's 535. However, I have also shot 440, 490 and 530 with equally good results. It's about the patch, IMO.
 
Thanks fellows what’s the best way to measure, telescoping gage and then mic?
If it is even number lands you can use calipers.
I've use a lead ball flattened just enough it won't drop in with a hole drilled in it that I put a wood screw in it. Press it in just enough to get lands imprint then measure.
 
As for molds, the Lee are serviceable. I really like the Lyman/Ideal iron molds. If you can find a 4 cavity iron Lyman or Ideal in your preferred size you can bang out a LOT of balls in a short period of time.
 
Every gun is different. I only have a 50. It doesn't like 495s at all. It likes 490s with a thick patch. Buy a variety of balls and try them before getting molds.
 
Bighorserider got it right. Try different ball diameter, patch thickness, & lube combinations to see what your particular barrel likes the best BEFORE buying a mold. You can measure all you want, but the proof is in the "shootin".
 
I have iron molds from Lyman, Saeco, RCBS and a couple more; but I bought them long ago when I didn't have to sell my car to be able to afford one. Maybe just me but the prices on them are staggering nowadays. So for years I've been getting mostly Lee molds and they are good. I have a T/C mold, JT bronze mold and some other misc. molds, and use them only on occasion. The Lee molds give yeoman service.
