These are good products for the low volume/beginner handloader. I have one so don't think I am throwing stones at anyone. It has it's place just like any other tool in the box!
The play is the cumulative of all of the clearances needed for the press to function properly.
I shoot in competition so I have several progressive presses. 3 Square Deals and an XL650. I started on an RCBS RS-3 then graduated to a Lyman Spar -T. I thought I was in seventh heaven on that baby! Still have those too by the way!
In my opinion, and everyone has one, for the serious, voluminous consumer of handloaded ammo, there is no need for anything over the XL650, but again, that's my opinion.
In 1 hour today, I loaded 500 rounds of 45ACP ammo for son #2 to use in PPC. I didn't have to work hard nor did I hurry. Just a steady pace with the monotony broken up by refilling the primer magazine and putting cases in the case feeder.
I suppose I should sell some of this stuff. I surely can't use it all at once!
