I should have caught onto matching the bullet and sabot before. The SSTs I have mike at 0.450" and the black sabots @ 0.495". Together they come out @ 0.505". The 44 caliber XTPs I had were 180 grains and are 0.428" in diameter.
Thanks for the heads-up on the bullet sizing pack; I'll definitely get one of those.
I have some Cerrosafe; probably ought to get an actual bore measurement with it.
