I understand that these bullets were made for either the Hornet or Bee, but has anyone pushed them to 33-3400fps?

YES, and you will love them!

They are my standard 223 loaded bullet for sage rats and prairie dogs. 14.5 grains of Blue Dot gives me 3250 fps in a 26 inch barrel ( and 24 inch also).

Winchester loads them in their WalMart 22/250 Remanufactured loads, ( 40 shells for $17.00 or so) and lists their velocity over 4,000 fps.

So you should be looking good Pete!

Cheers and Good shooting
