Possible Reloading Problem With 9mm (SECOND UPDATE)

[Cdog]

Happy to see you found the issue.

Ironically, I used a RIA Compact 9mm to work up my 9mm loads. It functioned flawlessly. I'm wondering if your chamber is not cut quite deep enough, and the leading edge of the case mouth is up against the rifling. This could easily cause excessive pressure. See if you can have someone make accurate measurements of the chamber dimensions and let us know.

I shot more reloads through the RIA this morning and they worked just fine, even some short plated hollow points. I ran them all through the Lee FCD and all problem seem to be solved.

Thanks for all of your help and suggestions.

I never had issues with my 9mm loads until I picked up a SA Range Officer. It's well known as both a more accurate then average gun and having a tight chamber.

After fighting it I bought the FCD and it's been 100% reliable. My old loads would chamber and fire in various other guns, including Beretta 92, various Smiths, and Hi Power.

I had a RIA that would do the same thing, but mine was 45acp. Pulled the barrel and the chamber looked a little rough in a few places. Took a cotton cleaning mop, put it on a cordless drill and ran it in and out with Mothers Mag polish until the few rough spots were gone. Took care of the problem. Got rid of the RIA and won’t ever own another one. The Tisas made in Turkey replaced it and is a much better gun.

This really makes me wonder.....

I could see an FCD working better on a roll crimp, but I just don't get why it would make a 'better' taper crimp unless the traditional seating/crimp die is somewhat faulty and it would be great to know why.

Having had all kinds of problems with 9mm myself, though, if it works, it works. The FCDs seems to solve a lot of bugs.

Don't know about 9mm, but the Lee FCD die for my .44 mag has a case sizer built into the die body. You have a bulge in case, for whatever reason, the FCD takes it out. I love the FCD dies. Makes the best roll crimp I've ever saw on .44 magnum rounds.

The primers look fine. This is the only pistol I have tried them in. This RIA had never malfunctioned with many factory loads including aluminum. I am quite sure of my record keeping as I put an old business card in every container of reloads with the date and powder amount.

Pull one & weigh the charge. If it chambers, it should go bang, so not a crimp issue.

There is no longer a problem.

I set the Dillon up for 9mm and thought I would crank out some rnfmj reloads and save my factory and reload hp's.

Based on the above information, I removed the Lyman taper crimp die and replaced it with the Lee FCD. I thought this would solve the problems and save me a step. I was smart enough to only load 20 rds or so. They would not work through the RIA! I replaced the taper crimp die, loaded a few test rounds again and then used the FCD using my RCBS single stage. Tested the rounds in the RIA today and everything is working fine.

Again, the problem is only in the RIA. It may be that it needs a finish reamer ran through the chamber. With the virus problem, I do not wish to take it to a gunsmith. I may mail it to them however.

Now, I can get serious about loading some more fmj round nose 9mm. I have a thousand bullets from Precision Delta.

Are you sure they were 115 gr? 4.5 gr 231 are about max with a 124 seated 1.070. Shot in my 986 the primers are flat and flowed to the edges, and difficult to eject.

Depending on ne bullet, 4.5gr isnt even close to max in any of my 9mm.

The lfcd is a generally fix for poor reloading technique. I just dont see how that helps a case from being stuck after firing. Something else is amiss.

Maybe a fix but it will put the correct type of crimp on the bullet also. Again I don't know what that would have to do with the case being stuck either.

All rmp dies, properly adjusted, apply the right crimp. The lfcd sizes the bullet inside the case. So your ammo will likely be more functional but less accurate.

The pistol works with factory loads. Compare your reloads with factory loads and find out where/what the difference is. I don't think I've ever had a problem with a round that passes the plunk test. When doing the plunk test the round should fall all the way in and fall out with no resistance, if not, find out why. The fact that factory loads work proves the fault iis in your reloads.
