Re: I Will the point of impact change?
Two years ago I missed the same doe twice, in fact, she watched me reload after the first miss and refused to run after the second miss! So if you ask me, then "YES" your flintlock can be off as much as three feet...particularly with a live target 30 yards away standing broadside, especially on heavily hunted SGL's!!!
Actually, my rifle was sighted in at 100 yards during the spring that year and I only fired 2 shots before the hunting season started in the fall to make sure it was still "on". Last year, I sighted in at 50 yards (typical open-site killing range) and practiced at that range through the summer up till hunting season started and I felt confident I would harvest anything within that range so long as I kept my powder dry. All went well until I had a buck 40 yards away on the last day of the season, when the gun misfired! I recharged the pan and aimed at a stump after the buck ran off...KABOOM!
I think the uncertainty of the whole experience is what drives me to keep doing it...very exciting...and frustrating at times, but humility is a good thing, right?
I killed the stump, by the way!
Bigfoot saw me but nobody believes him!
