Thanks for the links FyrepowrX.
I think I read TAFFIN TESTS: THE .445 SUPERMAG earlier while searching info. I read article again & the 1 thing besides resizing brass was this.
"Except for the case-sizing cautions, reloading the .44 SuperMag is the same as for reloading the .44 Magnum. A good heavy crimp is required both to keep bullets from moving forward in recoil as the big sixgun is fired, and also to get the powder started burning properly."
I don't have the problem that revolvers would have with bullet movement in cylinder. But the "good heavy crimp" to ignite the the powder properly was interesting. The loads I tested with the chrono had a reduced crimp on them than previously.
The articles were also interesting with Speer 240 FMJ bullets. I'm starting to compress loads at 31.3gr IMR-4227 with Sierra 240 JHP crimping in groove. So I'm backing this down a little. Not sure if H4227 & IMR4227 & Sierra take up same case capacity as Speer.
H110 loads listed in articles seem pretty hot also with Speer 240 JHP.
