Does the 308 Winchester have to be crimped? I am loading it for my Remington 788 bolt action and some people say crimp and some don't. I know in Autoloaders you should crimp but not sure about bolt action, magazine fed. I loaded them with 150 grain Speer Boattail, so should I crimp them or not or is this going to be a 50-50 answer? Thank you. 74man
