Hello everyone again!
Ok, so a question on another forum about penetration of ammo on a 3/4" Pine board got me curious enough to go out and do a test for myself. I thought it would be good to share it here on my blog.
I didn't go get or make anything special... I went and got an old dry pine board that's been in my shop for years, my .44 cal. lead ball ammo and slingshots. I stepped off 7 yards and shot several times not for accuracy, but only trying to keep the different band set groups away from each other.
Here were the contenders:
I shot my "Ultra Power" band assembly which is double tapered theraband gold which pulls approx. 30-35lbs depending on your draw and was chronographed by Joerg Sprave at 225fps and is at the top of the power game for non wrist-braced slingshots.
My "Gold Winner" single tapered theraband gold. It pulls approx. 14lbs. at 28" and has a nice balance of speed and power.
My New "Back Butterfly" long stretch bands. They pull approx. 14lbs. but at a 58" draw length. Fast and powerful!!!
And finally my New "Gold Butterfly" long stretch bands. They pull approx. 18lbs. at 58". Amazingly fast and powerful!!!!
The results:
Take a look at the pics but I was a little surprised. The most "Powerful" in terms of impact penetration was my "Gold Butterfly" bands. They sink a .44 cal. lead ball in 1/2 way or more.
Working our way up....next came the fairly good tie between the "Black Butterfly" bands and my "Ultra Power" bands. That was the most interesting because one pulls 14lbs. and the other pulls 30-35lbs. Of course one pulls and shoots in a standard way and the other in the extended butterfly style stance.
The least depth came from my "Gold Winner" bands but they shoot fast and flat as a good a target band should.
I would stay that ballistic gelatin would be a more consistent choice for this kind of test because of variation in pine density from tree to tree, species, humidity level, age etc; but I'm too busy for for all that. I really like simple anyway. Finally, I would conclude by saying, a pine board is not a bad tool for impact power/depth testing if one is careful and takes proper safety precautions. This was nothing fancy, just a basic "I wonder" test anyone could do, still I found the results interesting... hope you did too.
I'd love to hear what you think. Have a good one friends!!!
