LAST EDITED ON Feb-22-11 AT 06:21PM (MST)[p]Ft lbs is just a mathmatical formula that is most useful when comparing small, fast moving bullets. It squares the velocity, so faster bullets come out looking better. Useful for 270 and 30-06 type guns, but not too useful for big slow bullets in muzzleloading.
With a well constructed bullet of 300+ grains and in the neighboorhood of 100 gr blackpowder equivalent powder load, you are good energy wise out to 200 yards. BIG SLOW BULLETS KILL.
So what most people on here are trying to tell you is that accuracy is the main limiting factor with open sights. With lots of practice and a solid shooting rest of sticks, I set my absolute maximum at 150 yards but conditions would have to be ideal and that means very little wind, rock solid rest, etc. I have never shot at an elk over 120 yards.
Also, after about 130-150 yards, trajectory starts to be a big factor as well. With my elk hunting load of 90-95 gr of BH 209 and a 350 FPB, I can site it in to hold dead on out to 130 yards.
