I just got my flinter and am not expert on them for sure. I intend to hunt with it. I also intend to put a leather frizzen sock on the frizzen at least so there will be a much less chance of an accidental discharge. Also the frizzen sock will keep the frizzen dry so once removed we should be ready to shoot.
In wet weather I will use a cow knee although I hunt on wet days from a covered blind so that is not a major issue. I will still use the cow knee though.
From the little I have shot the flinter so far I think the way to be suscessful is to be always aware of the condition of the flint and frizzen, know that you pan is primed correctly (if not brush it out and reprime), and hunt with a sharp edged flint that has fired a couple times (this way you know it is set right. This I figure could be tested prior to loading and hunting).
Many posts ago I commented to a flinter that I had a lot of respect for them and the weapon they chose to hunt with. The more I use my flinter for target shooting so far, the more respect I get for those that use this style of rifle in their hunting.
By the way live bucks did you get a stainless steel model or the blued. Also how do you rate the fit of the rifle to the lock and frizzen. And what suscess have you had for sure ignition with the rifle. I have been looking at your rifle with terrible thoughts in my mind again.....

Although the 1842 rifled musket in .69 caliber does have my interest right now...
