jswitt99 Posted December 23, 2011 Share Posted December 23, 2011 Put through about 400 rounds yesterday and had an issue I hadn't seen before. About a dozen times, a new primer would not come out of the primer tube and into place for station 1. I started watching to see if primers were in place (really slowed things down) and one time I saw a primer that did come out, but on the return from the handle made the primer jump out... It was colder in my garage since I started reloading, dunno if that matters. What should I look at to prevent this? Everything seems normal...

Youngeyes Posted December 23, 2011 Share Posted December 23, 2011 (edited) Not sure what primers you are using. Some primers can vary in diameter and cause some issues. The tip on the primer tube needs to be watched closely as even a small amout of gunk or burr can make primer drop erratic. Check out BE's check list for primer function and maintenance on the 550b. I can't find the link but If BE reads this I'm sure he'll be nice enough to reprint it. Edited December 23, 2011 by Youngeyes Link to comment Share on other sites More sharing options...
CZinSC Posted December 23, 2011 Share Posted December 23, 2011 I had a similar issue recently. Have you taken the primer assembly apart lately and cleaned underneath the primer bar? When I did, I found a lot of buildup that was causing the primer bar to move erratically, sometimes causing the primer to jump out. Ironically I had cleaned it not too long ago. I over oiled the ram and the oil caused buildup under the primer bar to accumulate a lot quicker than normal. Link to comment Share on other sites More sharing options...
b2alphaplease Posted December 23, 2011 Share Posted December 23, 2011 I had that problem once, long story short, check the bearing plate UNDER the primer slide bar. Mine had most of the black coating worn to the bare metal, causing the primer bar to move forward erratically. Dillon replaced it. Tim Link to comment Share on other sites More sharing options...
