Did DC hit 200 fps @ 10GPP after all??

Mattock,, the bow was about 54 inches,, sometimes when trying to do that,, some of the reflex pulls out and its a wash,, shooting about the same,, but you could be right,, I think a little longer bow would hold the 28 draw a bit better,, since my draw is about 25 or 26,, I dont tiller them out that long unless its for someone else,,
Bassman,, I think your string may be a bit heavy,,but 45 @ a shorter draw should work fine for hunting,, have you tried something in the 54 inch length, I have good luck with them,,for my 25 inch draw

Ya Brad...44, 46, 48, 50, 52 54, 56, and I have a couple 38 inch sinew backed Osage bows. The longer ones draw 25, but some of the shorter ones draw from 18 to 23 inches. A guy gave me a Osage stave that was really long, and he had one end butchered with a band saw. I got 56 inches out of it, and put it on a 4 inch reflex form. Gave it a good heat treat , and sinew backed it. It had some checking on the back. After that I got my fingers operated on. Trigger fingers. Four of them are cut. When they heal I will finish the the bow God willing. I might make this one 50lbs, for 26 inch draw, and get somebody to shoot it through the chrony. My strings are either 10 strand B55 or 8 strand D97 on my bows. I will test this one with an 8 strand D97 string.

So true. For hunting Shot placement is key and having heavier arrow for good penetration on large game. Chrono Speed is just one indicator really. More importantly can you hit what your aiming at with enough penetration. There is a balance of good accuracy, decent speed and heavy hunting arrow with most of the weight up front. I don’t hunt with anything lighter then 550grains. I bump up to heavier when shooting heavier poundage bows 50lbs up. There are fast lighter weight bows relatively speaking that have higher gpp speed then hunting weight bows but I wouldn’t personally use them for big game. I’ve seen some 35-39pound bows that have higher gpp numbers but penetration becomes an issue on big game like deer, hog or moose. Might get away with it on deer if good shot placement. Much better results with slower heavier draw bow that has decent speed slinging a good heavy arrow with good foc weight distribution.

He was very careful about the testing and used a shooting machine. The bow appeared to be a Mark St Louis design. DC made several and he was struggling to get a bow that didn't take set. That is where they loose all the speed. I believe this bow is 41 or 42# if I remember right. I have never had a bow settle in at 200 fps. I have had a few in the 190's but not self bows. I think 186 was my best ever self bow.

Steve,
When Jordan flight shot that bow a few years ago, she immediately commented that it shot like no other bow. She still talks about how it shot! Unfortunately, at the time we hurriedly threw together a couple of random beat up flight arrows for it. We had no time for tuning or proper arrow matching which I believe would have made a huge difference. I’m sure there is much untapped potential in that bow.
I believe this bow was a legitimate 200 fps at 28” draw with 10ggp arrow bow. I very carefully followed how the bow was tested, asked many follow up questions, and I couldn’t find any obvious issue to say otherwise. 95% of the time there is a testing issue with high speed claims. Usually it is use of unverified weight scales for the bow and arrow, or using an inconsistent draw reference point (such as measuring 28” from the bow back), or drawing it to a different draw length than the one it was measured at, or relying on hand shot results instead of machine shot, but I couldn’t find any fault with DC’s bow. I consider DC’s 200 fps bow legitimate and an incredible achievement!
