ok I thought about it,, yes a 50# bow shooting a 700 grain arrow 150fps is shooting the same as a 70# bow shooting a 700 grain arrow 150 fps,,

in the first Bowers Bible Tim says a normal 70# bow should shoot a 500 grain arrow about 177 fps,,we didnt do much 10gpp back then,the first mojam stats are all 500 grain arrow,,
I know things have changed a bit since then,, but in my mind,, that is still an ok shooting bow,,today we would expect it to shoot a 700 grain arrow 165 fps,,
