For my Flintlock debut, I bought 5 cans of Elephant 3F with a date code of 1999, and 1 can of 4F with a different date...all based upon the pro-Elephant stuff I read on another forum from the same guy Mike was talking about.
Had mis fires, hang fires, terrible fouling, chunks of charcoal/wood left in the fouling, etc...could not continue the range session...was thoroughly disgusted to learn that "this is what shooting Flintlocks is all about"
Being economically minded, I tried it in a caplock the next Saturday...viola, same thing...so then I knew it had to be junk powder.
Bought some Goex and have never looked back...a 100% reliable, surperb price/performance powder and made right here in the good old USA.
I tried unsuccessfully to even give the Elephant away to local reenacters but couldn't find any takers...finally a couple years ago I poured out 4+3/4 cans of Elephant 3F in five 10' lines on the ground and set fire to them one at a time...it took many, many seconds for the flame to fizzle it's way along to the other end of a mere 10' line. (saved the cans just because)
Serious quality control problems...some lots were apparently manufactured OK, other lots were junk...my personal advice would be not to risk wasting your time, patches, balls, and gasoline to drive somewhere and plan to shoot ANY Elephant...get some Goex and you'll never regret it.
Moot point now, Elephant went out of business...
