I was waiting for Doug to fill in the details above, I didn't want to steal his thunder. As you can see, the DAS performed even beyond expectations. I'm a longbow guy, but man, I have to admit, those DAS bows are something else. Before I switched over to longbows, my recurves were all 85 pounds at 28 inches, and they were fast, very fast. Doug's lightweight DAS makes them look like weak sisters, seriously.
You asked about barefoot action? Well, I think Doug had his boots on, but on my second buffalo, Billy and I dropped packs and boots and went after a herd bull, thinking we would quicky get busted by him or his many cows, so it would be a short stalk. But on a bull that size, a guys gotta try anyway, right?
Two hours and 1.7 tenderfooted miles later, never being more than 70 yards behind the bull and several times being well under 20 yards, I laced him through the heart at 18 yards. He was rutting so hard he never even knew he had been hit. He died about 12 steps from there. Well, that's when I realized I had to walk back another tenderfooted 1.7 miles to get my boots, and even more importantly---drinking water. Man it gets hot in Australia!
For comparison sake regarding the DAS, I was shooting a 75-pound Howard Hill Wesley special, and Ipe arrows tipped with 160-grain Grizzly broadheads (860 grains total). On my first bull, which was laying down when I shot, the arrow went through the sternum, up through the heart, and lodged up in the spine with the fletching sticking straight down between his two front legs. I hit the second bull right in the crease, slightly quartering away. The broadhead cut a big rib horizontally, centered the heart, and stuck deep in a far rib. Doug's bow, being much lighter in weight, drove the broadheads clear out the other side of his bulls. Think what they will do on elk!
One more thing, everyone seems to be most interested in the penetration performance of the DAS, but they are forgetting its most important feature, and that is AMAZINGLY CONSISTENT ACCURACY. After two arrows, I can shoot the things better than any bow I have ever owned. If you want to consistently shoot knocks off and have ultra-tight arrow groups, get a DAS. You'll see what I mean.
P.S. I think we may have to get Doug back on here, as it seems he skewered a 6x6 bull with his DAS bow Sunday morning. He might have an interesting story to tell there too.
