I had this problem with my .45 auto rounds, now the 9mm are acting the same way.

I am trying to make 9mm 125 gr LRN rounds, and the length in the speer manual states 1.130 for these rounds. The rounds won't drop all the way into the chamber about half the time. I'm trying to use these in an XD 3" - any suggestions about length or crimp? I'm about at my wits end.
 
Springfield XD's have very short throats. I've got five of them, and they're all short in leade area of the chamber and require almost no bullet bearing surface exposed. You may have to shorten the overall length of your rounds by a very small amount.

I suggest you load a dummy round, no primer or powder, and seat the bullet they same length you are now. If it won't chamber completely, seat it a little deeper and try again. Do this until it drops in without any interference. This will give you the length you need for this particular handgun and then you can work your load up for that length.

Hope this helps.'

Have you tried seating the bullet and then crimping in two separate steps?

If the crimp is being applied before the booolet is completely down to seating depth, it will shave lead over the brass, enough to cause your problem.
 
Two things could be the problem, not taper crimping enough to remove all the case belling or not seating deep enough or too long an OAL to work with your pistol. The manual is a guide not a bible so seat the bullet a bit deeper until all of them chamber properly.
 
I had to do the same thing with some Berry's 124 grain FP. The recomended OAL in the manual was 1.120 and I had to go down to 1.035 to get them to chamber. It's not a big deal, reduce your powder charge and work them up.

Easy max OAL guide

1. Remove barrel from gun
2. Use a fired, unsized case
3. Start with fingers, the bullet of choice, into the case
4. seat bullet into case by pushing into the chamber, till it bottoms
5. Remove the mocked up cartridge, and use your calipers to carefully measure
6. Subtract .010 from the measurement, and use as max oal for that specific bullet profile.

I think you meant to say "subtract" .010" from the measurement......

Hope this helps.
