I crimp right in the middle of the grove. How much are you crimping. It takes a lot to buckle a straight walled case. Perhaps you should back off a little. You can always add a little more if you think it is not enough.

When I set my dies I raise the ram with the case in it. I screw the die in until it touches the the case. I then tighten an additional 1/4 to 1/2 turn. Never more than 1/2. But often 1/4 is enough.

When I do both with one die I set the bullet depth first. I do it with the die way back so it doesnt crimp. Then after the first bullet is the right depth I take the seater out to set the crimp. Once the crimp is set I put the seater back in and slowly screw it in util it touches the bullet that I just crimped.

Does that make sense?

Not really. Once it is set up doing both at once is much faster. I have both types.
