Depending on lead hardness, This can be done in 1 sweep no problem, LUBE is your friend here. I prefer to Roll mine over a Well lubed RCBS lube Pad with RCBS Case Lube-2, To much lube is Better than not enough. When you start the Press stroke DON’T STOP, Push straight through, With My press setup the way it is i have a tendency to Stop halfway through the Press Stroke to change Arm angle, That will GET YA Everytime, or nearly. 2 Steps would be a BREEZE, Go Through a .454 Push Through first, then the .452, I Have all of these sizers but i don’t use them, i size in 1 Sweep, They go through like Butter when done properly
As for Lube Grooves not Carrying enough Lube after being sized? That would obviously depend on the Depth of the Lube Grooves? If you go with a depth of say .040, Which is pretty Standard, Removing 8-10 Thou is NOT gonna hurt a thing. We are Sizing the Lyman Gould, And I’ve sized MANY other Bullets from 458-459 down to .451 with Stellar Results. Open your Calipers to 0.008 and look through, It is a VERY small amount you are Sizing
