Got rebel set up, tried once fired Lapua brass with Hornady FL custom die with expander moved all the way up, checked neck runout and under .001, after sizing it was over .001 and this die set up that way always improves runout, bullet had about .003 when done. I had die set with o ring under and noticed die would tilt slightly as case came out, so now I'm thinking this thing ain't aligned right but then noticed expander had come loose, ran another case up and then centered expander on case and tightened down, no more tiny tilt and runout improved, seated bullet and .001 runout, annealed another once fired Lapua case and it had almost .002 runout at neck, so ran it through and reduced it down to .0005, then I ran it through lee collet die and runout was a little greater but when bullet was seated runout was .0005. I then made some dummy rounds with miscellaneous brass and bullets I pulled and runout stayed right at .001 using same method of collet after FL die, also did body die on once fired Lapua and and collet and results were .0005 to under .001, works great with Forster seating die, seems like my bullet runout doesn't get much greater than neck runout and some not at all. The linkage does seem pretty loose on the down position and I moved it a little left and right but the ram just kinda turns on its axis a tiny bit but it doesn't move left and right or back and forth like my lee, can't feel any slop in the ram if I try to move it around so it is pretty tight. So I made about 15 bullets and only the first one with loose decapper had bad runout, all others .001 or less, seems to give consistent sizing and seating too, though I am still tempted to get a mec and see if it can do better, seems a lot of people are claiming almost 0 runout, maybe the Christmas of two presses. I will say that so far I don't see much difference between it and the rcbs Jr, but haven't done seating on junior, but I feel the Jr is a very good tight press, mine seems to be on the money.
