#1). You have set for yourself a bit more steep hill to climb. .17 is not the most widespread beyond the BB gun. But...
#2). there are "custom loaders." Supposedly to do this for a business or at all you should have a Federal license... (G'D' bureaucrats, go tea party)... This is also a "hooK" that might take you where you want to go. Ask in the gun stores which have to be licensed. Shotgun News has a list of licensed FFL dealers who might know someone or be doing this too. I don't know of a source for cases so the person will have to neck down .218 WCF cases. .17 bullets are available. Mr. Ackley published data. Mr. Corbin (Dave) on his web site, corbins.com, has a list of bullet makers who need a license to sell bullets and a). may do this too, or b). may know someone.
Then, if you ask around there should be a .17 shooter or two around. .17 Bee? Probably not. It is an older, weaker case from black powder standards and the hot rodders want a newer case like .17 Fireball. You have to buy dies... oh well... they already have powder and primers... Making cases (necking down) is not too hard. If they supervise as you use the equipment, legal... Luck.
