It all "worked" didn't it? We have the photos, we have the written accounts. So do flat bows but I don't see many around here using them. As did the model "T" but I don't see anybody here opting for that over thier pick'em up truck.
You know why you don't opt in for the old stuff? I'll tell ya...Margin of error/failure.
I get so tired of hearing about puttin "it" in the right place. No duh. In the traditional world, all you have is the best use of the materials that fall into that catagory, why not use them to your advantage?
Personally, if I have an arrow set-up that can punch through both shoulders of a 160 pound deer
within 15 yards I've just decreased my margin of error and opened up the front 1/3 of the chest area haven't I? Say yes, because I have.
Is the shoulder my intended point of impact? Certainly not, but it makes it easier to put "it" in the "BEST place" which is "just below and behind" the shoulder when I'm not subconciously worried about hitting the shoulder.
IMHO that's where a large number of gut shots come from...fear of the shoulder. Why fear it when you don't have to?
So if my 695 grain heavy FOC (21%) single bevel out of my little 53 pound laminated recurve happens to hit the shoulder, or the deers angle isn't "perfect", I don't care, my arrow is still headed home, and that deer isn't going far, if anywhere.
Case in point, my last 175 pound Illinois buck the shaft entered about 10 inches behind the shoulder blades alongside the spine, and exited (punched through completely) the sternum at the bend in the chest. Penetration stopped at the feathers. The deer went 10 yards and tipped.
Oh and he knew he was hit, he just about dropped to his knees. I kinda like having a shaft setup with that kind of performance out of such a minimal draw weight. Imagine the possibilities out of a 63 pound rig and 825 grain arrow set-up!
Don't tell me I got lucky, that shaft went through the top of the rib cage, entire chest cavity, and the center of the sternum with authority. Cedars and 125's have no chance of that performance. We also have the wrtten accounts of that don't we? Unfortunately very few photographs.
Are you going to push a 3 blade through all that with a 53 pound recurve? No chance. You going to do that with 10 GPP set up? No chance. Are you going to do that with a non-3:1 BH? Yes, I did it with an DB Ace. (Today I have SB grizzly's)
I had a shot opportunity I could take because of mechanical advantage. It didn't cost any more to create that opportunity either. Just some planning and a bit of patience.
