Wanting to experiment with making my own rifled barrels, I tried to find sources of drills and reamers. Found none. Any tips?

Drilling that hole from scratch requires some specialized tools and techniques. oil thru drills help a lot with chip management and heat. pec drilling also is a way of managing chips and helps a lot. coolant thru the blank is a plus when reaming and finish drilling.
Pec drilling drills a small distance removes the drill and does it again. on cnc or true deep hole machines this is a simple program or cam setting and the drill s removed at close to rapid travel and insert the same. On a manual machine 20" at .100 a pec is a lot of cranking.
