I do not plan on loading this bullet any hotter, but I do not think it is a max load.
Even if it is a max load for a 6-shot 45, it is not a max load for a 5 shot 45. It is also no where near the pressure levels of a 44. So if anything my accuracy could probably benefit from from an increase in the powder level and pressure level.

BFR Shooter,
as far as your reason for full-length sizing, your bullet should completely fill the throats of the cylinder thereby preventing the bullet from laying on its side. Mine are always centered in the chamber because the bullet completely fills the cylinder throat.
