I'm using an RCBS turret press and a Redding powder dispenser, and every time I throw a charge, a small amount of powder misses the case. The powder dispenser isn't perfectly aligned to the head, and when I run the case up, the drop tube causes it to tilt slightly. I've shimmed under the lock ring to square the dispenser up to the head, but it's a big pain, as I have to readjust it every time I change turret heads. If the head was threaded 1-1/4" I'd install Hornady lock n load bushings in the heads and square them up, giving me a "permanent" adjustment. I called RCBS and described the problem, and the rep is sending me compensation washers. I'm assuming these are bevel washers and should be way better than my haphazard shimming, but I still don't have the permanent fix. The heads have standard die (7/8-14) threads. Has anyone else had this problem and figured out a permanent fix?
