shooterDrew Posted February 24, 2016 Share Posted February 24, 2016 To start I've reloaded 15,000+ 9mm on a 650 in the last year. This year I picked up another 650 to be dedicated to 45. So far I've loaded maybe 1500 rounds working through numerous types of primers.... Now I'm on S&B which I've got 5k or so of them. I'm getting sideway seated primers all over the place.... Anyone know why??? I've never had this happen with small pistol primers in 9mm.... It's very frustrating and getting to be expensive!

RiggerJJ Posted February 24, 2016 Share Posted February 24, 2016 Don't know why it happens, but you can usually feel it happening. When it happens to me I remove the case right there from the primer seat station, remove the primer, put the case back, advance the primer wheel by hand, and press another primer into it. No wasting a bullet... jj Link to comment Share on other sites More sharing options...
StevenR Posted February 24, 2016 Share Posted February 24, 2016 Had this happen on my LNL and came to the conclusion that these primers are flat enough on the bottom that they would catch, not the one in the priming mechanism, but the one above it. So I polished the areas that could cause that catch and flip action, which seems to have fixed the problem. Don't know where or if that could happen on a Dillon press. Good luck!

zzt Posted February 24, 2016 Share Posted February 24, 2016 When that happens to me on my SDB it is always the plastic dispenser on the primer tube. When I replace it, the problem disappears. Link to comment Share on other sites More sharing options...
TDA Posted February 24, 2016 Share Posted February 24, 2016 (edited) Remove the shell plate and clean it and the platform. Then make sure your shell plate is rotating freely and snapping into the detente. I had the same problem and found that the detente ball was not snapping into the shell plate leaving the case misaligned with the primer punch. Haven't had a problem since and I load lots of LP S&B in .45. Edit: Also make sure the nut securing the magazine tube is snug.

anachronism Posted February 25, 2016 Share Posted February 25, 2016 And remove the primer slide, and clean both the race area of the press, and the bottom of the primer slide. Does your press have the stamped steel guide between the slide and the press frame? I don't remember if 650s need those or not. My 550 was terrible about doing this. Dillon ended up replacing the primer slides because my press had first generation slides, and they were always binding. Just keep an eye on your primer slide, and see if it jerks as it travels. The travel of the primer slide must remain smooth and steady or the primers could end up standing on end by the time they reach the case. Link to comment Share on other sites More sharing options...

Flipped the spring there, as it seemed to sit more correctly after flipping it (if that makes sense)... Also removed the roller bearing mod I had put on initially, and then tightened the shell plate back down and loaded up a quick 75 rounds. No primer flipping issue at all. Hopefully this has cured it.

alsipd Posted February 25, 2016 Share Posted February 25, 2016 I had this happening with 308 cases and realized I was using the small primer ram with large primers. Using a Hornady LnL AP. Link to comment Share on other sites More sharing options...
stick Posted February 25, 2016 Share Posted February 25, 2016 (edited) I load 9mm and 223 on the same press. I was getting sideways primers with the 223 but not the 9mm. As previously mentioned, I cleaned the primer system and removed all the small powder, and grit that seems to get into it. I also did a thorough cleaning of the press and i noticed that the plastic indexing ring was cracked. Dillon also recommended that I use the alignment tool. so far, no issues.

RePete Posted February 25, 2016 Share Posted February 25, 2016 Make sure your press and bench are solidly mounted without wobble. Link to comment Share on other sites More sharing options...
twodownzero Posted February 25, 2016 Share Posted February 25, 2016 If it's a 650 make sure the arm that pushes the case inward when you prime is adjusted correctly. If the case isn't centered you will have all sorts of priming problems. It takes a little allen wrench from the side to do it. Link to comment Share on other sites More sharing options...
perttime Posted February 25, 2016 Share Posted February 25, 2016 (edited) I'm pretty sure the 650 priming system is adjustable. Are you sure it is adjusted correctly for 45? Edited February 25, 2016 by perttime Link to comment Share on other sites More sharing options...

shooterDrew Posted February 29, 2016 Author Share Posted February 29, 2016 I took the shell plate off and cleaned everything well and then reassembled. I made sure that the detent ball was tracking correctly and now that it's back together I'm not having the issue anymore. I can't say 100% that I know what the exact problem was, but thankfully it's not happening currently. Thank you for the input from everyone!!

Jimk60 Posted March 1, 2016 Share Posted March 1, 2016 Lots of good info here. I have moved almost exclusively to S&B LP and SP. Both for price and quality. The only time I get sideways primers is when I am a little quick on the primer insertion push, and the shell plate hasn't fully cycled into place. This I solved by adding a slight pause on the upstroke when I feel the slight resistance from the primer. The slight pause gives the shell plate time to center. Basically stopped the sideways primers. BTW, I have the phenolic ball and the bearing kit on the shell plate. Link to comment Share on other sites More sharing options...

Ruffian Posted March 28, 2016 Share Posted March 28, 2016 Members 1 posts Posted 20 March 2016 - 08:31 AM Recently I began having problems with my 550 primer system. Primers in the cup were occasionally upsidedown or on their side. I was told about the weighted primer follower and tried that. No help. When coming down with the shell plate I was hearing a small click. Followed up on that and found that the primer cup was not centered in the shell plate platform hole. The cup was catching a very little bit on the shell plate platform as it came down. When the cup slipped free of the shell plate platform the spring in the cup rebounded, bouncy the primer slightly in the cup. Sometimes the primer got screwed up. I spent a lot of time trying to recenter the primer cup. Also tried cleaning and lubricating. No help. Finally after sitting in front of the press for hours, studing, I found the problem. The "shell plate platform" which is under the shell plate & home to the little ball bearing had turned very slightly. The two bolts which hold the platform go thru holes which are a little to large which allows the shell plate platform to turn some fraction of a degree. I loosed the two hold-down bolts, took up the slack in the bolt holes. Primer cup now travels smoothly thru the shell plate platform and no more up side down primers.

NickFL Posted April 1, 2016 Share Posted April 1, 2016 I've crushed way too many primers in my 650. I blame it all on crappy brass. The price is right so I don't mind the crushed primers too much. Now that I'm loading brass that I've fired at least once, I'm much happier. The biggest problem with crappy brass is that you sometimes have to put some real muscle into the handle to size it. When those power down-strokes end you are causing the entire press to shake and that is what usually causes the primer to flip. Or sometimes, it's just the quick stop of the handle that leaves the case not quite aligned with the primer hole. Link to comment Share on other sites More sharing options...
Almo Posted September 1, 2016 Share Posted September 1, 2016 Could be the S&B brass. I found their 9mm primer pockets were small. I get a lot of primers tilting or crushing when I load S&B Brass. Don't have the ptoblem with other brands. Could be the same on 45. If you have a primer pocket swager, you could try that. For 9mm, I just toss them. There's plenty of 9mm available. If you don't have a lot of them, consider tossing them. Link to comment Share on other sites More sharing options...
