Watched and having been in places like that i think I noticed that, in the second portion, somebody had done some shooting and were not as careful as you. There were a whole lot of pellet sized holes in the plastic roofing. Without a solid back drop I would have not taken some of the shots others did. Maybe it was a pass through and not a miss but I shoot my FX Dreamline Tactical compact on low power when inside. Don't shot where there's a plastic back drop but guarantee i won't go through metal roofing or walls. I always use the Hades and have never experienced a pass through on low power.
I was in a calf barn awhile back and the farmer asked to me to get rid of a few starlings that were nesting and messing in the calf barn. I sat on a chair nestled ove my tripod mostly hidden, and using my Daystate Pulsar .22 with a Pard 008 on it and waited quite awhile, All the doors were closed and there wasn't much light in there. I moved the Pard to IR and then could see in the dark places where they seemed to hid immediately after flying in. So far i have gottn half of 2 nesting pairs but need to go back. I have an aftermarket board in the Pulsar and shoot it inside on power level 4. It makes a loud noise when it hits a metal roof or wall but does not penetrate. Hades also with that rifle.
