If you can hit the x at 1000yds with your reloads, your loading is good enough for hunting too! What kind of hunting is your friend going to do with his 7RUM? Thin skinned deer, heavy skinned elk/moose/bear etc? Close range or long range?
The search utility on this site is excellent and you will probably find everything you need right there, but feel free to ask. I haven't seen anyone hollered at on this site for not using the search (like you see so often on other sites).
Welcome and enjoy!
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
