Triple 7 Powder

[larry ipock]

Have a jar that is half full and always kept dry. It's roughly 11 years old. Always ignites, but get different groups, (3 to 6 in.) low and wide at 50 yards with 100 gr. loose vs 2 50 gr .pellets which is on target. The pellets were bought this year.

I've always heard bp substitutes lose power with age

100gr of loose T7 is more powerful too than the T7 pellets. The pellets will roughly duplicate 100gr of Pyrodex.
