want2race Posted March 16, 2007 Share Posted March 16, 2007 I've been keeping an eye on this and think it may be getting worse. Loading .40 into 1x fired winchester brass, using Win SSP primers. The primers seat ok, little firm on most but they go in. Upon inspection, most primers will seat with one side of the primer just below flush and the other side of the primer just barely above flush. It's not very noticable, but it's still not perfect. I've tightened the shell plate, no change. Other than cleaning the shell plate (I just read about possible buildup, though I'm not loading bare lead bullets) is there anything else to check?

dillon Posted March 16, 2007 Share Posted March 16, 2007 See if the primer punch is no longer bottomed out in the primer slide. Using calipers, measure from the underside of the primer slide to the top of the primer cup. It should measure 1.410", +/- .003". If nrecessary, use a clamp or vise to reseat the parts, then retighten the set screw. Link to comment Share on other sites More sharing options...
