atbarr Posted September 4, 2014 Share Posted September 4, 2014 I have two 550's, one for .45's and one for 9mm. Just in the last week, the one set up for .45's, started throwing primers behind the press, or just to my right. Driving me crazy. Oh, and not 100% of the time, maybe 60%. Just a royal pain. Any ideas? Link to comment Share on other sites More sharing options...
Oldgoat03 Posted September 4, 2014 Share Posted September 4, 2014 Are these new primers or spent? Need more info. Link to comment Share on other sites More sharing options...

Youngeyes Posted September 4, 2014 Share Posted September 4, 2014 Check the primer cup and see if it is lined up properly. It may be catching on the edge and flipping the primer. It also may be gunked up. This would cause it to stick and snap forward, also throwing the primers. Link to comment Share on other sites More sharing options...
2MoreChains Posted September 4, 2014 Share Posted September 4, 2014 Check the plastic nipple on the end of the primer tube. If its buggered up it may not be holding/releasing the primers correctly. Link to comment Share on other sites More sharing options...
rdinga Posted September 4, 2014 Share Posted September 4, 2014 I had this happen one time and I had the large primer tube inserted while trying to load to small primers. I about went crazy and Dillon sent me several new parts until I discovered the true root cause. When I found it I was humbled. A worn plastic nipple will do the same thing.

atbarr Posted September 5, 2014 Author Share Posted September 5, 2014 OK, I finally emptied the primer tube, so I have enough for Sunday's USPSA match. I'm going to give it a through cleaning, and I'll report back. Thanks for the feedback guys. Link to comment Share on other sites More sharing options...
GrumpyOne Posted September 5, 2014 Share Posted September 5, 2014 AT, look to see if there are any spent primers that may be catching the slide...they will be close to the ram or close to crank end...sometimes they flip into those spots and cause the primr bar to act funny.

benos Posted September 8, 2014 Share Posted September 8, 2014 For reference, AT: 550 Priming Assembly Adjustment Notes: Thoroughly polish frame, wherever priming slide touches it, with green Scotch Brite. (Approx. every 3000 rounds) Wipe off Primer Slide with solvent or alcohol. Leave it all dry. At rest primer slide adjustment: Set so that one primer, dropped down the tube, goes all the way into the Primer Seating Cup, 10 times in a row. Angle of Primer Slide Operating Rod (13869) - Release rod from rollers and swivel it 180º so it's pointing straight up - it should be parallel with the Primer Housing Shield, or maybe outward "a little"; it should not be "inward" at all. Be sure both screws (14530) that tighten Roller Bracket Shell Platform (14280) from bottom (to the Shellplate Platform) are tight! Make sure Priming Seating Punch Assembly is fully bottomed out before tightening screw (13996): Measured from bottom of Primer Slide (13920) to top of seated Primer Seating Cup (13284/5), dimension should be between 1.125 - 1.220 inches. Be sure Priming Operating Rod Bracket (13887) is adjusted so it's within a few thousands of an inch from the top of frame/Toplhead. Be sure the plastic tips of all your Primer Pickup Tubes and the plastic tip on the bottom of the Priming Magazine are seated fully against the tubes. Grease the short end of the op-rod where it inserts into the bracket clamped around the primer shield. Link to comment Share on other sites More sharing options...

Is the term "buggered" now a technical term in Dillon lore? I'm pretty sure it is in the UK... Link to comment Share on other sites More sharing options...
