I crimp all of my semi-auto ammo with the Lee Factory Crimp die. I crimp all types of bullets cannelure of not. This not only helps secure the bullet, it improves accuracy. YMMV.

Is it "Needed" no. Does it help, yes.

Of all my bolt action rifles I only use the LFCD on one. It is defiantly not required, but improves accuracy, plus it makes me feel better.

There are those that crimp for some of the Big Boomers so the bullet stays put while in the mag. I do not.

Note that Sierra is now manufacturing some of their Highly accurate MatchKing and GameKing bullets with cannelure to give the Accurate shooter the option of crimping.
