Well, I have managed to get a couple deer with my flintlock rifle - it is a custom Pennsylvania style 50 cal (actually 49 cal) with a swamped barrel and nice maple wood - I got the gun in 2010 and have killed 4 deer with it (nothing in 2012 or 2013) and I have been happy with it - not the first flinter I have owned and it is a tack driver - accounted for two gobbler's at 60 and 62 yds about a minute apart (the time it took me to reload) back in 2010 - has won me a bunch of plunder at shoots and hopefully someday I will get to bag an elk again with a flinter.
A target - I shot last summer 50 yds off hand - as I was working up my current hunting load - 5 shots shoot-n-C 6" bull target
One of the deer I got this year - high spine shot - complete pass through DRT
Two turkeys I shot with it
My 62 cal smoothbore built in 2007
Button buck I shot with my smoothbore 75 yds complete pass through ran about 40 yds
