Thanks for the info. I'm curious the purpose of jamming into the lands as opposed to increasing the powder charge a little. Is it for centering the bullet better or just for pressure/forming?Basically just jam the bullets .010-.020 and use a mild load of 7828 or H1000 (55-59 gr). Those Game Kings should work fine.
N570 is the undisputed speed king for the 6 UM. It will give you ~100 fps over anything else. Pretty much every 6 UM barrel seems to shoot 66 gr N570 with a coated 115 NR DTAC at .060" off really well.
