Hi I'm new here on the site and have been lurking in the back ground as I read the various posts. I am also new to reloading. I have a couple of calibers to reload for starting with an Savage in 270 win (for LR hunting), Remington in 308 win, and another Savage in 223 rem (for LR varmint control). Question I picked up some Hornady 30 cal. SST which has a cannelure. Is it neccessary to crimp when reloading this bullet or will it be fine not to?
