My guess, double charge. Heard lots of folks that use the Savage rifle are very pleased with its performance. I have black powder pistols/flintlocks/caplocks and hunt with inlines with subs.. When hunting, I weigh each powder load (after getting the weight for average volume recommendations), for consistency. I could be off 5 grs either way and get about the same results in accuracy. My inline can take up to 150 grs by volume, but it kicks like a mule. I wish they would have posted more details, but the lawyers are keeping quiet for the big payout. You know the difference between a lawyer and a catfish? One's a bottom feeding scum sucker and the other's a fish. My daughter (attorney in Boston), told me that one.
