How often do you replace your flints? Still new at the flintlock and went out the other night for an hour looking for a doe. Didn't see anything and it turns out I'm gladI didn't. On the wayout Iwanted to shoot the load out and found it wouldn't fire. After looking closely, the flint was the issue. Lesson learned, like bow hunting, replaceables should always be new before the hunt weather you think they need to be or not. Still, wondering howlong flintsshouldlast. This one didn't give me any issues in the last practice session but was obviously dull.
