Velocity loss with 3f Goex
Very odd. The other day while shooting in high humidity, 95+ degrees, I chronographed several loads from my T/C. Loads used CCI caps and .50 320gr Lee cast lead maxiballs. 90grs of PyrodexRS ran around 15-1600fps. I then chronoed some 80gr 3F loads. They only ran about 950-1000fps!
Can anyone come up with an explanation for this?
Powder deterioration? It has been stored in the same place as the Pyrodex. The chrono was not at fault, as I tested a Pyrodex load after the 3F. Velocity was consistent with the earlier loads.
