Don't jump off the nearest bridge just yet BN, life ain't as bad as you think. Most RO gauges indicate TIR. 'Total Indicated Runout'. Actual off center is 1/2 of TIR , so your 5s out are really only .0025" off center the 3s, .0015" and etc.
Feel'n better already ain'tcha?
Presses? There are two schools of thought, and nice tight well made press hoping that all the parts involved are square to each other or one that allows the brass to find it's own alignment to the die(s). The COAX is the latter, by design or dumb luck I can't say. Of course a standard press with it's ram turned down .005" or so for some longitudinal slop does a pretty darn good job too.
