I may have been mistaken about 4320 being discontinued. I bought the last three a local shop had because I thought I had read or heard somewhere that is was being discontinued. Was back in last week and they had several one pound cans of it. I bought one more pound so I have 4 or 5 pounds now.
Probably could use other powders but in Marty's myopic, 17 Remington world, there is 4320, Hornady 25 grain HP's and Remington 71/2 primers. No other components need apply.
