Todd - real interesting test. Thanks for sharing. I couldn't help but notice that the lighter arrow lost about 90 fps in 100 yards and the heavier one lost only 60 fps.

I blew away two chronographs so far with a muzzleloader - the sabots still have quite a bit of power at 10 yards. One solution that works for me is to put a 4 X 4 wood block across the front of the Chrony. Worst thing that can happen is that you will hit the stakes or the sunshade - both of which are easily replaceable.

While turkey hunting this morning, we witnessed a largegobbler (that wouldn't come in) at about 100 yards. At the conclusion of the hunt, we speculated on the odds of hitting that bird at 100 yards. Even discussed a wager of breakfast on the outcome. My buddy, without having apin zeroed for past 40 yards,shot first and hit an 8" X 12" target put up at this distance. First try. I didn't even shoot. Arrows are expensive. Boughtbreakfast. .
