Not sure how much an RCBS Rock Chucker goes for these days but Im shooting 1/2 Moa or better on mine. I don't think a more expensive press is going to shrink that group at all. Don't get caught up in the hype of crazy expensive presses.
I have heard good things about the dillon press.
This is what I’m currently using and not sure any equipment changes will improve consistency but open to trying more expensive press. Getting .001 runout or less, .04 grains load consistency (1/2 kernel) Seating depth .001 consistency.

But - with a good barrel and the right load you may duplicate my results with a $50 lee die set, a hammer and a powder dipper !
I'm curious what features made you go with the AMP, there is a handful of options and prices vary widely. I've been leaning towards the Annie...
