Is it necessary to crimp 223 ammo ?

If you are shooting a bolt action or single shot, there is no need to crimp.
The debate tends to get interesting when dealing with autos. I always crimp when loading for any auto. The inertia of the bolt slamming a cartridge can push the bullet back in the case or if the tip of the bullet hits something while being fed. I have seen this happen enough times with a variety of autos to recommend crimping.
You will find people that disagree and say they never crimp for automatics. My answer has always been "Maybe so, but all military ammo is crimped"
On my "redneck progressive" turret press, the powder check uses a neck sizer die w/o expander. This works well with boattail bullets(which is what I load on this press exclusively.
