Do I have to crimp?

You need some crimp, even if it's just to hold the bullet in place. More crimp if firing out of a semi-auto as the cycling of the action can drive the bullet into the brass.

edit-Sorry, I see what you meant. No, you don't have to crimp because of the cannelure.
 
Nope!

Really comes down to what u are shooting but I dont even crimp for my AR anymore!

Bolt action I would not bother as long as the gun feeds smoothly.

I had a stevens 200 i loaded quite long and ocassionally the bullet would set back when I cycled the action as it hit the edge of the feedramp coming out of the magazine.

Just cycle some rounds to be sure before you start shooting.

Having a bullet set back far enough will ruin your day! Possibly much more as well!
