Had a great day at the dairy!

Some nice real world testing AirgunBill! Looks like the gel mimics pigeons well.

This is the last test block we played with. Only one fragment made it through the block out of about a dozen shots. It was only going 99fps after the exit. Lol.

Something to think about is even as hard as pigeons and other pests get hit with standard slugs they can still be getting hit twice as hard. 

I look at hunting videos a lot differently after so much testing. And always enjoy them when Bob_O is behind the trigger/cam.


 
Here's the real test data that @swish is referring to. 

20% NATO Ballistic Gel. 2" thick block pass-through test results. 

2 Shots ea. showing how much velocity (energy) remains after pass-through.

1- .22 cal. 28gr. HP 910 FPS @ POI - 548 FPS after passing-through 2" thick gel. block.
2- - Same - - 557 FPS 

3- .22 cal. 28gr. HP 875 FPS @ POI - 547 FPS after passing-through 2" thick gel. block.
4- - Same - - 553 FPS
-----------------------------------------------------------------------------------------
5- .22 cal. 28gr. Frag. 910 FPS @ POI - 000 FPS No pass-through 2" thick gel. block. 
6- - Same - - 000 FPS

7- .22 cal. 28gr. Frag. 875 FPS @ POI - 000 FPS No pass-through 2" thick gel. block.
