How accurate do you gotta get to play this long range game. I read an article that you shoot little chickens, off-hand at 100yrds. You then shoot 200, 250, 300..(with sticks). I bought a H&R Trapdoor froma "re-enactor" fella but don't know if I'm good enough to hit targets. How big are they at the different ranges? I finally found a range to shoot to 300yrds. I could probably hit a real-life sized buffalo at 300. ps: Eastern too.
