I've gone through about two pounds of Hodgdon Triple Seven FFg in the past few months in all of my muzzleloaders, both traditional sidelock and inline... However, this deer season is the first time I've hunted with it... I did not get a shot off on opening morning, and did not fire the charge out, but rather, I left it in there and hunted several more days (putting the rifle, a T/C Renegade sidelock) through several cold/warm cycles... I took the rifle to the range to do some shooting after a couple of weeks and got a misfire, followed by a delayed shot. (hangfire)... I'm wondering if anybody has noticed that perhaps 777 FFg tends to absorb moisture more than other powders... One thing I did notice was that the flash hole, which I had cleaned carefully using a pipe cleaner prior to loading, was gummed up a bit... Thanks in advance...
