Thanks for all the thoughts. I've gone over the primer slide with a fine sandpaper before, and have also experienced problems with the bolts on the primer slide assembly being to tight. I've solved all previous primer slide issues since I installed a roller bearing kit. I think njl's advice will help... slow down and inspect the primer end of each case as it goes into position !. I'm thinking going too fast may be causing some "bump" which is flipping the primer in primer cup.

I have the correct primer cup installed. I have dedicated my old SDB to LP for .45

This has always been a pretty consistent problem. I've been loading for 47 years, originally on a Rock Chucker, then a SDB starting about 1986, and then the 550b for about the last 5 years. I've always had this intermittent problem both on my SDB and the 550b. I just recently started to get PO'd about it

Shell plate is adjusted properly and everything is clean.

When loading mixed 9mm range brass on my 550b I experience about a 2-3% loss of primers, normally when a primer gets inserted sideways in the primer pocket. I also may loose some when the primer edge becomes deformed by a crimped primer pocket, and I have to dispose of that primer. The result is that out of every 1000 primers loaded into the primer tube I may wind up with only 970-980 successfully loaded cartridges. Is this common? I try to keep everything clean and aligned properly so as to avoid mechanical press related problems. Is this loss rate typical?

That is what I was thinking. Have you loaded those same bullets for pistol, and if so, how do they perform?

Sorry for the multiple postings on this topic... I kept getting an error message when trying to post. Ultimately it got posted multiple times.

I currently load bayou 147g flat points over 3.2gr TG for my 5.25 XDM. I'm looking to buy a 9mm PCC in the near future, and wanting to standardize on a load for both my pistol and PCC. Would the bullet profile I'm using work well or do I need to make a change? What do most feel is the best all around bullet profile and weight for both applications? I really like the cost and performance of the Bayou bullets. Any advice is appreciated.

Thanks for all the replies. It appears this particular bullet DOES need to be seated for a short OAL due to it's shape, and it appears that the 3.8 TG load is within acceptable limits. That being said, I plan on backing up to 3.4 TG and work back up... hopefully to the 3.8 load since it is very accurate in my pistol. Thanks again for all the responses.

Haven't put them through the chrono yet. The plated bullets I was running were around 1020. I know I need to chrono them, but was looking for someone else's experience first...

I have been loading 9mm 124 gr RN plated bullets from Berrys, X-treme, and RMR with 3.8 TG, at 1.150 OAL for my XDm 5.25. I recently got some SNS coated 125gr RN, and after performing the "plunk" test, find that I must load them to 1.110 OAL to function properly in my XDm. I've shot them with 3.8 TG with good results, but I am concerned that the shorter OAL might be raising pressures too much (no evidence to support this). I'd appreciate anyone else's experience, comments, etc. Has anyone else found they have to load this bullet shorter, and if so have you decreased your powder and still gotten good results?
