9mm Rounds won't seat

[cfmitch]

Thanks Jack. I have loaded this round previously and have always had problems with it. I have noticed before that if the round will not fit in the case gauge then it will not cycle through the pistol. (Desert Eagle) Yes, I am using a crimp die on the round. However, I will try your way just to see what happens. Thanks again.

I'm going to assume you're using a die that taper crimps- most 9mm dies do. If you are roll crimping, switch to a taper crimp.

This was my first thought also when I read your original post.

What is your COL? Is the bullet contacting the lands?

Some problems to check, OAL, proper crimp, fouled chamber, bullet material on case mouth. Do use the barrel's chamber as a gauge, out of the gun.

If you are using a taper crimp or profile crimp, the seater should be a seperate die, otherwise you will cut bullet material as the bullet seats and the case mouth is squeezed down. If cast bullets are used, it is imparitive that the seater be seperate or you could get lead / lube buildup in the chamber severe enough to cause a round to fire out of battery.

Are you getting the case FL resized? If your not getting the case sized all of the way down you may have a bulg just above the rim stopping it from chambering.
