To make loading as errorless as possible I only use LRMP in the 460 cases. I prep, flair, prime and put them away until deciding which powder and bullet.
Wonder if that's why the gun is not that dirty with any powder.
LRMPs are used in 458WinMag loads with 50gr-55gr of 4198 and at 60gr-70gr+++ I use LRP all with 300gr JSP/JHP bullets.
Loading for a 3.5" and 8" 460 is the current fun chore.
Having grips that fit your hands perfectly is a plus.
