Awesome for you!! Firstly, do not alter the gun............EVER! Also, most people would suggest that you practice with the same ammo you are going to hunt with, as different ammo's often shoot to different points of aim. I ended up getting into reloading, and have not ever regretted it once. I bought a cheap Lee Challenger Breech lock press, some dies and odds and ends and started reloading. I bet I probably spent about $250 to get started. It is like following a desert recipe. It is NOT hard to do at all. (I am not remotely handy, yet make excellent ammunition)
Surplus .30-06 ammo dried up about 25 years ago. You now own "The RIFLEMAN'S RIFLE". Respect the history and provenance of the gun, and it will still be knocking down animals 100 years from now.
If it has a steel buttpate, slip-on recoil pads are allowed �� but take it off between shooting to avoid marring the wood underneath it. I've seen lots of stocks with faded finish that I know was caused by those pads being left on for years.
