First of all, expect an expensive hobby! First, you'll want to start reloading, then you'll want to add new barrels, grips, etc... Its an appetite that cannot be satisfied!
In all seriousness, you have an excellent selection of barrels. The Fireball is a great short barrel varmint caliber, and the 7-30 is an excellent all around deer caliber. I've recently learned that trigger jobs are very easy to perform, and these guns are extremely accurate.
Good luck!
