I saw where Jeff Bartlett lists his supply of 7383 as new production single base powder, All the posts I see on here lists 7383 as triple base. If in fact it is single base will it be safer to work up loads with instead of triple base? I want to use it in 243, 308, 270 and 30-06 with jacketed bullets and cast bullets when I get around to it if possible. I'm on the fence with this powder and need a nudge to buy some.
