Are you looking for precision in repeatability? The machining of matting surfaces? Press with tightest tolerances/clearances between moving parts? etc...................
yep ... and any input on if this matters , some say a little slop is ok because on high end dyes the dye will match the surfaces to tight tolerance's anyway once the case and bullet start to mate in the dye or once the case enters the dye for resizing.
If you consider only presses, I measured the results I was getting and found my Redding T-7 gave me better results than my old Rockchucker for seating bullets. I don't do any full length sizing on the T-7 though only neck sizing and seating. I use a new Rockchucker for full length sizing and then seat on the T-7. However, dies make a huge difference and don't be mislead into believing that only neck bushing dies will give low bullet runouts. Test and make sure on all dies. In resizing my 300 SAUM for match use, my plain jane cheap RCBS full length sizer gives the best and lowest runouts which are far better than my Redding bushing dies.

Excellent info ... absolutely struck that your RCBS FL is producing resized brass that is so strait. Something I will take into consideration when im trying new dies. Im honestly struggling with run out when seating with my RCBS standard dye's ... I have couple sets of Forester Ultra seater dyes , I also have foresters bushing bump dyes and they're FL dies and although I can commonly get run out inside three thou , sometimes a thou ... Im producing to many rounds with 5 thou which im not happy with. I would prefer to be constantly producing ammo
with run out less than 2 thou
Ive been reading that even with high end dyes your expander ball can warp your neck when you pull your case back out even while neck sizing with a bushing dye. Thus causing you to have run out problems. I know for a fact my RCBS case trimmer/ outside neck turner is not cutting straight, It will be one of my starting points.
Off the topic of run out and onto pressure and back to presses ... I like the idea of the force dial indicator on this press , it will give you a idea of the consistence of the hardness of you brass. I believe this will definitely give you an idea ... or help you determine how consistent your pressure will be before you go to the range . Especially when you know your brass has been prepped consistently and weighed.

Another clip of some high end case prepping done on Lapua brass I had dug up on AS

Thread is a little side tracked now ... but all good
I will also add , although im shooting pretty good at 1000 yards ... I want to be a lot better, and more consistent " specifically " I will say that I commonly can get velocity spreads between 40-60 fps ... inside 300 yards it dosnt seem to matter, but at 600 is where im really starting to notice it , although some guys seem to think im shooting very good at 600 , a more experienced shooter will notice there are issues. What im reading is a velocity spread as big as 25fps at 1000 yards is going to make you completely uncompetitive... Im looking for virtually no run out and single digit velocity spreads ... I wont be happy until it happens
I again I remind members ... im looking for info from guys that have experience with 1000 yard shooting and guys that Bench and are getting extremely consistent velocities more than anything.
Thanks you guys have been very helpful
