Never had shot them indoors before so the flash and bang was a bit surprising. They don't seem nearly as ferocious out at the farm. Love that they go exactly to point of aim unlike my plinkers where I have to hold a bit below 6 o'clock. 
Sad - Realizing that I can't put anything back into the brass except the social/hunting loads until I get a care package from Bayou Bullets. (at least it's on order and shouldn't take too long to get to Houston)
