I have a decent amount of experience and have had good sucess over the years hand loading, but it has been exclusively for use in bolt guns. I've got a upper on order from Monty which should b ready sometime in the near future. I think I'm going to get into loading 77gr OTM rounds for it and was wondering what dies are preferred for loading semi auto specific ammo?

Also, does anyone know a part number or where I can buy Nosler 77gr with. cannelure?

Thanks.
