Posted 23 Aug 2017 I ran across a cache of Super Slow powder from Hi Tech Ammo I had in storage for my Puteaux's, but forgot about. This powder has been sealed in the factory jugs, stored inside 20mm cans with desiccant. Cans have been stored in controlled climate INSIDE since day 1. I have 6- 7 lb jugs and one 5lb jug. This IS the correct powder to use for your Puteaux or Hotchkiss 25mm cannons. $280 for the 7 lb jugs and $200 for the 5 lbs jug. Buyer pays shipping and any haz mat charges. USPMO only. Thanks, R.L.
