I posted how I solve this problem years ago. EGW was making their special die then as well, this issue is as old as the Glock. What I do is through sizing, just like some factory reload manufacturers do, except on a smaller machine.
This is the 40S&W set up to eliminate the Glock bulge. The 9mm set up is similiar.
40S&W Lee FCD and a 9mm lead sizer push rod
Modified die box to fit over die
No lube needed, just have at it.
The other issue, unrelated to the Glock, is rebound. When we seat a bullet, the brass will swell out to fit around it. If the bullet diameter is too large we will notice a couple of things. First is the look of the ammo and second is it often won't chamber properly. You can buy a chamber checker and go through all your ammo, good idea. You can remove your barrel and use it, another good idea. You can buy a Lee FCD and resize it on the 4th or 5th station, VERY BAD IDEA. If you squeeze a lead bullet down in size it will not rebound any but the brass will. This causes the neck tension which holds the round together to drop to nothing. Not exaggerating, bullets will often fall out if the round is tipped upside down.
To solve this issue, make sure you use sized lead AND custom polish your FCD inside carbide ring to the proper diameter. As delivered, the FCD is too small for many lead bullets, even if sized, and you will need to polish the carbide ring to a larger diameter. LEE will do this for you if you ask. Sorry I can't remember the specifications guys, its been years since I modified mine but I would guess .002", it really depends on your chamber. Factory jacketed ammo does not usually suffer from this problem, if you use lead I suggest you buy a second LEE FCD and modify it. IPSC ROs will tell you they see alot of crappy reloaded ammo, these two proceedures will cure half of the stoppages we see.
Shoot Safe,
Cheers,
