Yes some a little more than others but they all get crimped to a certain point.
My .223/5.56 & .308 get a heavy crimp but my .300 BLK & 6.5 CM get a light crimp.

I've tried it both ways with all my rifles. My experience so far is that a crimp generally has not had any effect on accuracy (hurt a little in my 22 Hornet). Consequently, I crimp rounds used in a tubular magazine, and use the sizing die with the decapping stem removed to smooth out the bell (light taper crimp?) on cases with cast bullets. No crimp on anything else.

Only if loading for a lever action with a tube magazine such as 30-30 and 35 Rem. I have aBLR in 358 and a savage 99 in 308 but they feed from a spool and detachable clip style magazine so I do not crimp those either.
