So after hearing all of the debate over "to light of an arrow" i decided to run some tests of my own. Last year we were in need of reducing the doe population on our land and a friends and hear in michigan the DNR is in need of money badly enough to allow you to buy all the private land doe tags you want so no problem there. So i decided to put my money were my mouth is and try a "light arrow" at high speed and here was my setup. Mathews DXT high country speed pro max arrows and 2 blade 100gr rage at 347 FPS with a total arrow weight of 280 grains. Well below the 5gr per lb rule but that is not the subject here. So first doe 12 yds broke the spine going in and exited the chest (so far so good). Second doe 37 yds broke shoulder going in and coming out complete pass through. 3rd doe 23 yds double lung pass through. 4th doe 53 yds broke 4 ribs going in double lung and pass through out the other side. 5th and final doe was 33 yds quatering away broke 4 ribs and the opposite side shoulder on the way out. So while my "tests" are not a thousand years of stats i think if the light arrow was going to have a problem i would have seen something. So with that said i believe i will not have a problem shooting a lighter arrow as long as i can send it fast enough. And if i can push a 2 inch cut through a good amount of deer there would be no problem with a cut on contact tip or a smaller broadhead. Just my opinons.
