45lc - Mihec 462 GC Cramer with TrailBoss ?

[HikerLT]

Looking for advice to load 45LC with the Mihec 462 GC Cramer bullets, using TrailBoss powder.

the Mihec 462 lists weights :
small HP - 326
lrge HP - 314
solid - 337

all of the TrailBoss load recipes I have found in searching seem to stop at 300gr bullets.

Thanks !

I'd look up the procedure rather than trust to my memory, but the formula for Trailboss in straight wall cartridges as I recall is: Mark a case where the BASE of the boolit seats. Fill to that level with Trailboss. Weigh that amount. 70% of that weight is your starting charge. They warn to never compress it, as it radically alters it's burn rate.
