Hey guys, I also posted over on snipershide, but I wanted to get some of your expertise as well. I've been trying to figure out where my bullet run out is coming from. I tested my fully prepped necks and most of them I can get to no more than .001" TIR on the necks. I'm using a redding comp seater, and after seating my bullet runout varies from .001 to as much as .007" TIR. case prep as follows: lapua brass, skim neck turned to neck thickness of .014-.0145" hornady 208 amax rcbs JR3 single stage press redding shellholder held in place with rubber o ring redding body die Trim and chamfer on wilson trimmer and with vld tool clean ID of necks with steel wool on bronze brush after tumble redding comp neck bushing die (I also tried with a lee collet die and the neck runouts were higher, up to .002" TIR so I stuck it out with the redding bushing die) redding comp seater, seat then rotate case 1/2 turn, then complete seating a few things to note is that in using my wilson case trimmer I need to rotate the case holder to get the cut all the way around the case mouth. I basically rotate the case holder until there's no more cutting by the blades. Also, my vld trimmer in the wilson trimmer has been cutting unevenly, I have a k&M vld tool on order. I've tried floating my dies and not locking down the locking ring but still to no avail. All my cases after seating measure .001" TIR or less on the necks but the bullets still measure anywhere from .002 to .007 TIR with the majority being in the .004-.006 zone. Any thoughts would be great. I also have a forster co-ax coming in the mail hoping that will help as well. Thanks in advance.
