YouTube video by Pro Archer Shot-Coach (uploaded Aug 19, 2022) demonstrating a 110# two-piece traditional bow fired into plywood and a pine 2x4 to evaluate kinetic energy and penetration. Presenters discuss measured/estimated energy (about 160 ft·lb for the 2x4 shot), arrow mass (~1000–1200 grains), and velocity (~200 ft/s), observe shattered/split arrows and deep penetration through multiple plywood sheets, and conclude the bow delivers high kinetic energy comparable to some firearms-level foot-pounds for certain loads.
Questions this video answers
Approximately 160 foot-pounds.
About 1,000–1,200 grains (speakers say "thousand grain" and "almost 1200 grains").
About 200 feet per second (speakers say "200 foot per second").
Arrow penetrated multiple plywood sheets—described as going through two, three, four-inch pieces of plywood and poking out the back.

Hi.
Welcome to great flights.
All right, you guys ready? Well, hold on. Oh, yeah. It's all the way through. Oh, yeah, I work perfectly.
All right, let's put a stock on it. Shoot it off the shoulder.
Yeah, let's shoot it one more time. I don't think it's going through that. 3/4 inch ply. I think.
Well, that's 5, 8.
Yep.
Got it.
Right here dead on. It didn't even have a problem with that.
It didn't even stop.
All right, we gotta go thicker now.
You think it'd go through an elk shoulder blade?
Oh, yeah, I think it'd go right through his shoulder blade. No problem whatsoever. Oh, I foresaw that guy. Heat the glue. Heat the glue gun up.
But let's just take a second to.
Good boy. What are you going to name it? Fluffy.
I think we're going to call it Fluffy. Please don't break.
5,000. Good girl. Good girl.
Pine two by four here. That's 160 foot pounds in there.
160. Oh, wow.
That's a 22 mag. Number 22 ornate.
No, no, put this 2,000.
Yeah, put your velocity in what your.
Your grains is much closer.
42 gallons.
Yeah.
That's only like 40. Yeah, like 40 grades at 2. As far as foot pounds of energy, we're in rifle, like not huge rifle, but like small handgun rifle with more carrying weight. So we're shooting thousand grain arrow at.
200 foot per second.
Ish.
Always slightly terrifying doing that. You guys ready? All right. Wait, wait.
Do you think it'll go through?
Yes. Yep. Okay.
I'm gonna say I don't think it'll.
Quite make it, but assuming I can hit it.
All right, ready?
Yeah.
I know we broke the tip off.
It shredded that arrow.
Absolutely annihilated that arrow.
It tore off the end. It tore off the nut point. Shredded arrow. The carbon actually bent the insert broke. No, it broke it off the shaft of the tip. Well, to be fair, we kind of had that on an angle.
Yeah, we need to also, we need.
To shoot straight on. Oh, it's in there. Yeah, it's almost. If that would have been. If it would have been straight, it'd be poking out the other end because it's on an angle in there.
I think with a broadhead, it would have gone right through because those field points have a lot of drag.
It shredded that insert.
It broke that right at the end of the shaft.
Oh, yeah. See that? The fill point is still in there. That's a. What did Ryan say? 160 foot pounds?
Yeah, 160 foot pounds.
That's intense. You want to try broadhead on that two by four show it, or shall we go back with a field point from straight on?
I think we go with.
Take a.
Field point, grind the edges square like a vodka.
Yeah, but why wouldn't we just use.
It broadhead then bodkin has more structural strength.
Okay.
And we have a really cool knife grinder.
Oh, we are over the power of a 32 auto. Really? Yeah.
130 foot pounds in a 32 auto.
We're at 160.
A nine millimeter is like 300. This is a thousand grain. Now it's moving 1100 fast.
Almost 1200 grains. Yeah.
So it's moving an eighth is fast. I think my math's right on that. I might be totally wrong.
All right, I'm gonna put the point on, and then we're ready again. You want to do the. Shall we do the bodkin point or show, like, brush?
Long haired guys. These things are scary. Those are hair grabbers.
Nope.
Look at that. That'll work. All right, let me cool that off.
The vodka. Homemade vodka. You know, somebody could shoot this bow all day long. And here we are. Got to string it with two hands. Yeah. Ready? Yep. Got it. Oh, no. Oh, no.
You missed. No, you didn't miss. No, I didn't. Smack dab right on it.
Split that board. It split it the backside too. That's an insane amount of power Weight.
Tube came out the back and bent.
Literally kinked that thing. There was enough stress that it pulled that out. And that's a light tube. That had to be some. Oh, that's not good. You know what? How are we gonna get that out of there?
And this isn't what the medieval archers would have shot.
There is no question. That would probably go through two shoulder blades.
Oh, easy.
It's a two piece. That's. That's a sleeved bow. So for that to be holding up under that kind of force, that's. That's gonna be. That's a good deal. Ah, there we go. What is all. Ooh, what's all that? Oh, that's pieces of. Well, that was my last 50 grain insert. So now I'm gonna have to add another weight and put a regular insert in, which is fine. That will work. So we'll get another arrow, put another weight weight in, and then another insert.
I could cut a stock out and have a stock on it in like 10 minutes. Craftsmanship is not really the point of this. The point of this is Functionality. Just a slingshot.
Ch. Yeah, this is.
This is a bad idea. That kind of looks cool.
I'm not gonna lie. It's gonna be like that.
I gotta shorten that stock up.
When will this be available on the website? Maybe by Tuesday.
So most Crossbows pull about 150 pounds, 175 somewhere in there. But they only have like a 14 inch or 20 inch somewhere in there of power. This has a full 20.
Hey, let me give that a whirl. Let me give that a whirl. You know what? This would suck in a ground blind. I'm not lying. Well, I got my huge amount of weight. This is gonna make it about a little over 1100 grains. It's not gonna shoot very straight. We need to be a lot closer. Oh, no. Yeah, because I don't want to. Where that thing explodes by the time it hits. Because there's no fletchings and stuff.
Yeah, it might be going crossways. That's about the right.
Yeah. That's not a good thing. Oh. All right. So this arrow, it went through both sheets of plywood, but we broke the arrow off here. I just screwed it onto this. It actually broke the weights in there. It shattered those, but went through this sheet completely. And then it got all the way through. You can see it just poking out there. It went through two, three, four inch pieces of plywood. So we got a lot of energy on this thing. But as you can see, there's some massive damage here, which is pretty common when you're shooting into plywood or anything. But we wanted to see what was capable of. So lots of kinetic energy out of that bow. So that's gonna be it for today. Thanks for watching. We're gonna be doing more of these.
