Skip the once fired brass, unless it was fired in your rifle.
Lapua and Norma make good brass in .30-06, which will last many reloadings if not resized too much. Buy some headspace guages and only set the shoulder back 0.0015 - 0.002”. Quality brass, carefully prepped is the foundation on which good loads are built.
Barnes TTSX are my favorites for hunting, the 150 grain 0.010” off the lands should work well with the H4350. Many people like Nosler products, the Partition is still very popular. The Sierra Game King is another that is easy to make run well.
FJG, a guy just starting off will have a much easier time with a tangent ogive than a secant ogive.
OP, if someone with experience reloading lives near you, ask for help setting up the dies and adjusting everything initially and life will go smoother.
Read at least two different manuals on reloading, one of which should be by the bullet manufacturer you decide to use, before doing anything, buy good calipers and use them.
The stickies at the top of this section have lots of helpful information.
Welcome to a rewarding and enjoyable facet of hunting.
