I am encouraging my dad to practice more with his 300 win mag for an upcoming elk hunt, but his sporter weight 300 win mag beats him to death during extended range sessions. I was wondering if I could reload some rounds to ~30-06 performance. I haven't found any such loads in my manual, but I am curious to know if any manuals have a load that would be suitable. I am willing to order something different, but I have a bunch of 165 grain bullets that I would prefer to use.
