ah, yes... like a studious erm, student, I slugged the bore prior to purchasing the molds. Max diameter readings I got were - Chamber: .429" Muzzle: .430"
I did however read that only .001" over was the cast diameter to aim for so I got a .430" mold. I guess that means my bullets shouldn't need to be sized then eh? Maybe it's even a bit on the small side?? Only one way to find out.
The only thing I can think of is removing the seam from the bullet? each bullet has a very small seam where the moulds join together, and are .002-.003" over in those spots.
Should I be sizing the bullets to get rid of this, or will the bullet still be seated centrally with it?
I think I'll size them to .430" to remove any high spots. Worst case is it does nothing I guess eh?
So lube, size, lube it is
Then on to loading them up.
