Blackhawk 38-40/10mm Conversion. Same mold?

[jonp]

I was looking at a Buckeye Convertible in 38-40/10mm conversion and wondered if you could use the same boolits and mold in both. Anyone have one?

had a vaquero and another one with 1 digit more in the serial number back before I let my dad talk me out of them.
I have only had one 40 caliber mold, the magma engineering 38-40 rnfp mold.
the SIL uses it in his 40 weak now.
