Taper crimp ??'s

I've been reloading alot for revolvers and am now starting to reload for some semi-auto hand guns.  I have 45, 40, and 9mm.  I have read that these all rely on the case to headspace the round.  I know that the taper crimp is supposed to remove the belling to be sure the round will chamber freely.  I also read that I should not be able to push the bullet into the case.

I have loaded some 9mm rounds and set the taper crimp to remove the bell.  The round slides into the barrel and stops where it should.  My problem is I can push the bullet into the case if I press it down on my work bench.  I have read a few stories about Glocks where the bullet is pushed in causing over pressurizing and major malfunctions and don't want this to happen to me.  Maybe I'm just too strong and can still push in the bullet even though it is crimped properly.

How can I be completely sure these bullets are properly crimped?

Thanks

I suggest you make a couple of dummy rounds and cycle them from the magazine into the chamber 2 or 3 times, then measure how deep the bullet has moved. If it moves less than .005", then don't worry about it. Alternatively, press down against a bathroom scale. The crimp should hold to about 30 pounds of pressure.

Thanks, I have a shipping scale so I will pushing to 30lbs.  I think my problem is I am over worrying and pushing alot harder than 30lbs.
