50 fps is alot and takes alot to get it,most can't even come close and like I said,50 fps out of the same bow using different arrow weights is LESS of a difference than the chart shows.If changing poundage,then the difference is more because you are increasing the stored energy which in effect changes the momentum and ke by a much higher percentage margin.


If you are using 1 pin,you should make it around a 25-27 yard pin(depends on setup)and it will be much more accurate for you at most hunting distances out to 40,that was what I was trying to say about 1 pin users.


Then,that speed isn't nearly as much of a factor.


Trajectory charts are awesome for 1 pin users and you don't have to get nearly as much speed as you thinkyou need.


Most people would think that a 5 yard miss at 40 yards with 50 fps difference would be 4-5(or more)inches.Rick's picshows that not to be true.
