That is very strange, and seeing as I have zero knowledge about the XD I'm afraid I can't comment on WTF is going on. NEVER heard of a 9mm chamber with the lands so close in that some bullets would not completely chamber.
Are you by any chance using the Lee factory crimp die to make sure the OD of the loaded round is correct??
Also, are you using new brass, or once fired? If it's new, the inside of the case mouth has to be chamfered to remove the small lip on the inside of the case mouth. If you don't do this, it could increase the OD of the loaded round and make it hard to chamber.
Now: Seating bullets deeper to make them work in a 9mm may or may not get you in trouble, but it will raise the pressure of the round for SURE.
Since you mentioned the 40, I can tell you that seating the bullets deeper WILL get you in trouble and probably cause a kaboom, and you really need to cover your azz with this caliber. The OAL listed in the manual must be religiously adhered to, and you need a good, solid taper crimp of at least 3 mils to hold the bullet in place. many 40 Glocks have gone to the Happy Tupperware Grounds when a bullet got set back into the case when it slammed into the feed ramp.
Frankly, I would call up Springfield and ask them what is going on, just to see if the internet gossip is right or wrong. The only other thing I can think of is that maybe your seating die is set down to far in the press, so that you are applying a taper crimp to the case WHILE you are trying to seat the bullet. THAT would definitely cause a bulged bullet which might not chamber. Can you run an empty 9mm case all the way up into your seating die without encountering ANY resistance whatsoever?? If not, then there's your problem.
