Looks for Range (1/11)

  1. Sorry about that guys... I was missing the obvious. I found it.... Went back to something I read in the Mk7 set up. "Make sure the stoke always bottoms out" They are talking about on the cam. As in make sure you always have a solid cam over. What was happening was because of where the dies were set (to fully bump it back), if I did a calibration at that point. It would stop just short of full cam over.... everything looked right bottoming out on the shell plate. But it wasn't doing a full cam over on the 650. So that was my culprit on the shoulders all over the place. No matter how I adjusted the dies, seemed like I was chasing my tail.... It was driving me nuts. Just ran 500 308 lc and all passed the gauge. So that set up with do it on one pass. So if your in that boat. What I did was calibrated so it would cam over, then adjusted my dies down into that with no new calibration. Don't know if that's right, but it fixed my problem. Thanks for all your tips and tricks over the years, I learn something every time I come hear. Wanted to share something that had be stumped for a day....
  2. Just talking out loud.... I think I am fighting spring back in the brass, and my rates of not passing the gauge were higher, until I upped the dwell time at the top of stoke, that's what got me to 90% passing on the first pass. Either that, or some flex in the press that's random. But I don't know, that's just a guess. When I used to use a single stage I never had this problem. It just shows up any time I try to do brass prep on a progressive (and that makes me question the spring back theory). How are guys doing one pass brass prep on a 650??? I have seen several talk about it, just wondering if they fight the same thing.... Or is there something obvious that I am missing... (it wouldn't be the first time). Thanks, any ideas or recommendations are welcome.
  3. Hi there, everyone. Long time lurker... first time posting (out of frustration). My name is Dave and I am from the PNW. I love this forum and get so many great tips tricks and learn so much hear. To start off, the problems I have having. Consistency. I am preping once fired LC. 90% passes the case gauge, say 2% is slightly over sized (as in smaller than spec) and about 8% is under sized, (won't set flush in the gauge). It's not the rim, because turning them over the base slides into the gauge. Is this "normal", I hate having to gauge all my brass. What I am running. 650 with a MarkVII. Die one is a Lee universal deprime with a Fast and Friendly decap rod. Station 2 is a swage it. Station 3 is a RT1500 with a Dillon trim die, 4 is empty, 5 is a Lee sizing die with the depriming tip ground off so it won't crash into my press (this is to re set the neck, one last shot and getting the shoulder right, and getting rid of any burrs from trimming). Just getting frustrated..... I should be able to process this stuff with the set up.... but what am I doing wrong. How do you guys process 223, 308 on one pass? Or does it have to be ran twice to get it right, and if so, what set up? The other issue is the Mk7/650, I can't do a calibrate cycle with the swage it.... I have to take it off, install the primer punch and block. Calibrate, then take the priming parts back off and re install the swage it.... It doesn't seem like I used to have to do this... seems like I used to be able to calibrate with the swage it installed. Wondering if something has changed with my press, but I can't see anything, just that.... and it seems odd. Anyone else have this issue? Or is that just how it is, and I am not remembering right from my last time processing brass (a year or so ago....). And yep seemed to have the same problem with consistency then as well.... Thanks guys, Hope you have a wonderful day. Dave
