A couple of years back my wife using a Darton recurve that was 42 pounds at 28", she pulled to about 26&1/4". A large doe came behind her while she was sitting on a downed tree trunk, it passed by her at about 4 yards. As it was leaving it turned a bit giving her a shooting window, but just as she released the doe jumped. The arrow struck the right rear hip, cut a slot in the hip bone and continued all the way through and buried ferule deep low in the front left scapula. The arrow was a 420 grain tapered cedar, left wing fletched with a right wing 125 grain original Grizzly, file sharpened, simply filing the main bevel from heavy to light strokes, I flipped the head with one short stroke flat on the back, one light stroke on the main bevel, and then a single serration with the teeth of a Grizzly file from back to front on the flat side edge. That poor doe did not stand a chance with that hit. Not saying a thing against shaving sharp, most of the time I make her arrows shaving sharp. This time I merely wanted her to have a couple of extra arrows in case the birds came through. I did not expect her to shoot a deer with the older arrow. This was the way we used the Grizzly heads when they first came out. Most of our arrows were made right wing in those days, but a few were done with left wing feathers. I myself had switched to left wing bevel Hills with left wing arrows for my right hand longbows, but a few of hers were done with left wing fletching and right wing broadheads. I know that technically that it is wrong, but every deer hit with the miss matched combo put the deer down fast. This was the only time that one of them did not get a pass through, but then considering it was only a 37 or 38 pound bow at her draw and the arrow was only 420 grains and hip bone and the low end of the scapula got in the way, results are results.
