I kind of want one too, with a brake please! LEE's standard sizes are close but not quite perfect and require you to order custom to get special stuff done. The .356 is good for 99% of my dealings but some times I'd like a .355. Ditto the .430", and .401", usable but I'd buy some others if they were readily available outside of special orders. They never even made one in .375 cal. or 6mm, outside the custom options. I'm grateful they market a standard .510", as Lyman only does .512".

Several revolvers in 10mm class I've measured have been less than .400" throats, 0.398-.399". It's the way the reamers have been made. A .400" pin gauge will not pass. So generally ammo with a slow ojive and .401 bullet won't fit either. I've opened several up to get around that for cast bullet shooting.

Still it's better than the old days where you had a .400 (or smaller) cylinder and a 0.403" bore. I think modern 10mm bores are a true .400" groove to groove.
