After reading dark1961’s post about Kevlar backing, I jumped on the idea, and ordered this

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F131493616729

assuming heavier is better...his weighed 7 oz per yard, this is 14 oz. it has the carbon fiber look to it...didn’t cut easily with scissors, but a sharp blade sliced it...I bought 2 yards, so mine came in a large tube, 5’ long..I unrolled it, and cut one strip which gave me 3 layers on my backstop...I hung all 3 from the top so the were “curtained in the trap...pellets went right thru it, kinda snagged a fiber and pushed it on thru the next,and the next...22 caliber at around 800fps.... ive gotta rethink this...maybe fastening them tight to my 1/4” steel plate is the answer, for sure more layers...I’m gonna try 6 layers flat against the steel backer...

I’m also using a dense rubber composite “welcome” mat and i’ll Put it first, then the Kevlar stuff...it seems like it should work ok, with some changes...if the layers of Kevlar are flat against something it might keep everything in...

i use a hardened steel plate at the back, because 0n rare occasions, i’ve had to fire center fire rifle stuff into it..(much to my wife’s dismay)

My knowledge is limited but I've always seen Kevlar described as single use (at least per area) for disrupting higher power projectiles and always backed by a plate to stop them. Half the time I see it mentioned as pellet catcher, it seems to fail after a few shots. The other half the time... the topic just disappears (which makes me think those attempts failed too, and they didn't want to discuss it anymore :) )

I'm still intrigued by the 'chain mail' concept but just don't have a real use for one on my propert y. I can shoot what I want, mostly...I may build one to the specs I have in mind just as a test this winter.

17Hornet, I just tested the Kevlar yesterday and was very pleased with the outcome ,except for one thing. Noise. when hung loose the smack of the pellet hitting was very loud . Understand I was shooting at 12"to test penetration and pellet damage. I fired pellets at 753 fps 20flbs, 873fps for 21flbs, and 910 fps for 21 flbs. Pellets were all .22 and both Csmn 14.3 hp and JSB 15.89 domes. The harder 14.3 Crosman was the only pellet that broke through one layer. All others were stopped but showed denting (broken threads) back to the third layer. The softer JSB crushed and expanded slightly more than the harder Crosman. Photos will follow after more testing.
