I was at the gun show a week er so ago. Guy at the table across from me had 7 cans of Hodgdon HS-7 for 10 bucks each. By Sunday morning I traded him 8 rounds of Winchester 25-35s and 18 rounds of Remington 222 Rem mag ammo for 'em all. The powder was sealed new old stock in the old cardboard Hodgdon cans.. Going to load it in something..well some of it..Loading pistol rounds I'll probably never use it all. Should still be good. Dry out here..and still sealed..Ball powder lasts forever.. I hope
