I've been seeing post on why my arrow did not penetrate. Or why some mech heads didn't work or no Penetration. When you have bad penetration on a shot stop blaming the heads. Look at the arrow and total weight. And do you have enough to operate that head.
Most of the time you see a mech fail on light arrows or low poundage arrows.
What we are seeing is that the market sales speed. Years ago a bow was rated at amo. That is 60 lbs 540 gn arrow at 30. Then ibo cam arrow and that is where the market took us
Now let's look at mech heads. I do not know the brands I do not shoot them. But a few years ago I believe rage came out with one that would open as little as 45 k.e. To me this means all others are above this.
So let's look at this. Let's look at average 28 in shooter at 70 lbs shooting a 350 gn arrow and a ibo bow of 340. That bow has a k.e of 77 There should be no problems with a mech head.
Now let's take same bow but turn down to 45 lbs with same 5 gn per pound. Now arrow is 225 gn. Now ke is 47 Now we are getting limited on what mech head to use. Not enough k.e. To get head to operate.
Now use same set up but turn to the average 25 in for young Women. Now that same set up gives us an k.e. Of 38 Now we are below the one mech that tells us you need at least 45 k.e.
So how can a low pound short draw person compensate for this. It's not speed. It's weight. So now let's look at same bow. 45 lb 25 in draw but take arrow to 8 gn per lb. the arrow is now 360 gn. Now we have an 43 k.e. Still be low the min required on the 45ke mech head
So as you can see for low poundage and shorter draw lengths why mech heads should not be used.
In my opinion for low pound bows and short draw the arrow should be around 8 gn per lb. and a good cut on contact head.
We all have seen people kill with what I'm saying we should stay away from. But how many are lost because they are shooting arrows that I'm saying to stay away from.
