I was going through my late grandfathers reloading supplies looking for anything that said .308 or .30 cal and I found several boxes of Speer round nose and flat nose soft point bullets. And my question is what would be the intended use of those types of bullets? I think I have seen that some of the subsonic .308 ammo was using a round nose bullet correct? I am brand new to the reloading world and apologize if this is a stupid question. Thanks for any information.
