High FOC stability

I’m shooting a pretty high FOC arrow, about 28%. I built up some Judos to match the broadheads and field points for stumping. This morning I took a shot at a stump about 20 yards distant. On the way, about 15 yards out, it hit a bent sapling about 1/2 inch or so in diameter where the head hit. The impact was great enough to knock the rain off the leaves. The arrow went sideways, then in the last few yards the arrow righted itself and stuck solidly and straight into the stump about four inches low from where I was aiming. Now, who knows where the arrow would have hit if I hadn’t hit the sapling, but that is corrected itself so dramatically was amazing. I’ve noticed that my arrows seem to be effected very little compared to the lower FOC arrows I used to shoot, but this was an example that I could really see. Pretty cool. dwc

Yep. When our little group shoots outside, I am never afraid of a little brush. My arrows go through without incident. While others are squabbling like geese about taking such a shot. I just smile, shake my head, and move on to the next target.

Deniers live to deny. Neither fact or example impresses them. But at least they always comment with enthusiasm about how much the targets shake when my arrow hits them. And they always complaign about how hard it is to remove my arrows from the target 😆

Very cool bit of real world information David! Thanks for sharing. Too bad you didn’t get that one on video.

Nice. I’m currently shooting just shy of 28% as well. And I’ve noticed a similar thing numerous times when shooting out in the open and my arrow happens to get hit by a gust of wind in flight – the nock end might “kick” out a bit, but then the heavy head pulls it right back inline again, and it keeps tracking.

Yes, it’s pretty cool. I’ve seen it happen on smaller impacts, but nothing like this one. I cut a small Hemlock branch off once and arrow went on to hit the mark I was going for. This one was like slow motion. I wish I had it on video, too. thanks, d

What I’ve seen in my own messing around is that the heavier the arrow, the less it is affected by strong wind or limb strikes … and the more of that heaviness is up front, the more profoundly stable it is. And before I tried it for myself, I was an adjunct member of the Flat Earth Society. 😆

I’ve been to the edge of the Earth myself. dc

This story makes me think of turkey hunting this spring. I called a beautiful bird in from a long ways away. When I knew he was behind a rocky outcropping, I sneaked into position where I thought he’d come out and called a couple more times. Just like he read the script, he came down the slope through the brush and stepped out at 12 yards. As the arrow flew, I saw it deflect off a blackberry cane and sail just over his back. It makes me wonder what would be if my arrows were heavier up front !!

Essentially the same concept as sectional density for rifle bullets, which is why long/heavy bullets are better at stabilization/restabilization than short/light bullets of the same caliber.
