High poundage bows are for guys with lil' ............ with todays Cam designs a 60 pounder will send arrows as fast as mid-lates 90s/early 2000s 70- 80+ pounders with the same weight of arrow. and kill just as if not more efficiently as they are built with a higher brace height and shorter power stroke with an easier to shoot bow.
Yes I just bought a 70 pounder and own another 70 pounder ... but shoot them it about 63, the new one I dont know... Its so smooth and the draw is such that it doesnt feel like 70 I might shoot it at 65 (with a 350 grain arrow I should get 320 out of it ... at 65 pounds its said I will get 318 with a 325grainer ...my software says I will get 311 at 63 and a 339 grainer ..... my 60 pound max I shoot at 50(ish) (281FPS with a 339 Grain arrow)
