Of the compound shooters that I normally see, the average is they have been hunting for about three years, so they think they know everything there is to know, because they saw it on TV. Some can shoot tight groups at the indoor range, most do not ever shoot an arrow from a tree stand. They set their pins at twenty yards and set their tree stands either right on the deer trails or the nearest possible tree, so what does the bow sight do? I was told by one that they do that so some else does not put one up between them and the best spot. Almost every year, I hear about someone not being able see his pins through his peep, so he takes a guess without it and hits high and wide.
I tried compound for one year back in the early 70s, I could shoot hunting arrow groups as accurately as I could with BW and Hoyt FITA bows. I found that target groups and a single good shot on a live deer are not the same thing. I am better with a stickbow. It seems that judging all things hunting by target groups is getting to be more common. Try only counting the first two arrows. The real advantage of the traditional bow, for me a longbow, is shot versatility and shot timing. That takes practice, like anything else, but it is an area of shooting that can be improved on for many. As a predominately ground hunter, that is what makes or breaks a successful hunting shot for me.
