You can definitely reload rifle ammunition at home very easily. You just need to collect the brass cases after you've shot store-bought rounds or just go to an outdoor range and collect buckets of brass cases since most people just leave them.
The one time I "reloaded" rifle ammo, it was to work up a small-medium game load for a sporterized Springfield 03A3 .30-06 I ended up with as a teen. By then my father and his hunting friend were no longer using that round, so we started with a box or two of new brass like this: http://www.cabelas.com/category/Reloading-Brass/112555980.ut...
