There are a lot of ways to save some dollars. shooting pyrodex loose for one.i can assure you that a load with pyrodex loose can be made to be as accurate as the pellets.i use STS primers exclusively in my triumph and my Knight wolverine and i bought 1000 of them, which is far cheaper to do than 100 at a time.what are the 777 primers for? and what do they do that the STS primers won't? the pyrodex in the loose form can be used in place of your goex also, in order to save some cash..side lock rifles shoot real well with pyrodex !! i use blackhorn in the triumph and pyrodex in the wolverine with conicals. those 2 powders will cover about any rifles one can shoot.
