Hi I have just started to reload 9mm and I am having a problum with getting the bullet to get a good crimp. After I crimp I can still turn the bullet in the case but can not take the bullet out. If Lower the Die and more I will hit the case holder dose and one have any ideas that might help me....Thanks for your time!

sounds to me like a resizing problem, do you have your resizing die set correctly? also what brand of brass are you using?? with my 9mm and 45 acp loads I dont even use a crimp the case mouth already has enough tension that I feel it is not necissary to use a crimp. what brand, type and diameter of bullet are you using?? sounds like your case mouth is to large for the bullet diameter but the crimp is grabbing and forming a groove which would allow it to spin but not pull out, then a wrong size bullet diameter would explain why your crimp die doesnt have enough adjustment. By any chance are you using copper plated lead bullets??? I had a similar problem with berrys plated bullets and remington 38 special +P brass.

Are the bulelts loose before you crimp them? If so, its a resizing/bullet problem.
If they are tight before you crimp, you might be crimping them too hard, squeazing the bullet diameter down a bit and the brass springs back, leaving you with a loose fitting bullet.
The crimp you use for a semiauto (maybe revolver round as well, but I don't know as I don't reload for any revolvers) is to remove the belled mouth of the case only, not to hold the bullet in place.

For revolvers I use a roll crimp and for my autos I use a tapper crimp. You shouldn't be using a roll crimp for your 9mm ( if you are) With the dies I have this is a seperate step and a fourth die.

thank you for all your help. I'm using pmc brass, the bullets are gold dot spears they are 115 grain the diamerter is .355 yes I am using copper plated lead bullets. Do you think that is my problem? If so what should I use instead?

Check the bullets ,I got a box of bullets a few years back that were slightly undersized.
When you expand ,only expand enough to just sit the bullet in the flare.
Is the taper crimp die pushing the brass up against the bullet ?
Are the dies new ? Steel or carbide ?
I have a old steel 45 acp sizer that is worn out ( over sized ) due to lack of sizing lube.
You may need to replace the sizing die.

I think Briman hit it on the nose you are crimping too much. Start all over again and follow the instructions that came with your die set to the letter, and you should be alright. When you bell the mouth just bell it so the bullet will just stay in the case when you invert it. If you get frustrated, walk away and come back to it later. Good luck.
