Yes,yes and yes again, it will greatly mininize range estimation(the greatest problem with archery equipment)....But speed without accuracy will do nothing to put meat in your freezer(you will spend too much time pulling your arrows or bolts out of the dirt or whatever else you might hit by accident) I must not be the only one, every bow & x-bow company ads are related to speed(even the custom recurves and longbows,"purists" that they are,have ads that surpass some compounds of ten or fifteen years ago)How about the gun manu's with the short magnums, how about Hornady light mags, how about thenew 17cal(which by the way is the hottest round to hit the market lately) how about the 204 Ruger, they can hardly keep them in stock. And do not forget Weatherby, he made a good living making the fastest and I might add accurate round. The 257Weatherby is probably still the premier round for almost any medium game, very very fast and accurate. Mr Weatherby said it best "speed kills" but without accuracy it means nothing..........
