i have a lee press with the 4 hole turret and disabled the indexing device. so now i size all at once, twist the turret, and seat all at once. way faster.
plus i can leave the dies in the turret and remove the whole turret and replace with a different set for a different cartridge without unscrewing the dies or losing the setting accidentally.
slowing me down is weighing charges and priming on the press. i got the throwing charges idea down, and now i am going to buy a hand primer. should be nice to speed things up.
Don't buy the RCBS.
