    Yes or no on what? Crimping the bullet in the shell? If so yes, your die should seat the bullet and slightly crimp as well.

    All rifle dies will crimp unless you set them up not to. It is a small roll crimp. Do you need to? I dunno some say yes some say no.....

    I say yes, use a crimp on any round that will be in a magazine or clip.
    Magazine surge can move the bullet farther into the case.

    for semi-auto definately. not crimping can easily cause bullet setback which result in excessive pressure and turning your pricey semi-auto into a hand held pipe bomb...

    i heavily crimp my 223/556 and 308/762 30-06 and anything that gets fed to a semi auto.

    same dont crimp for bolt action long as your loading one ata time not using the internal mag. a light crimp is good as recoil can still setback the bullets or chambering can do so if the bullet is hitting the ramps.

    i crimp ammo that isnt for single shot use

    The only ammo that I crimp is pistol, .444 Marlin and .300 Win Mag. I have been loading for over 30 years and regularly shoot M1 Garand, M1A, and other bolt rifles without crimp and have had no problems.
    A light crimp does seem to level out deviations in velocity.

    No you don't, but should you notice problems with set back involving an autoloader or heavy recoiling rifle, then maybe you will.
