Ok so this has nothing to do with rimfires but I just had to share this with you folks....but be warned..this is a video that just may make you wet your pants!!! there are two links below. The first one is for the video ya gotta see. The rifle is a 577 T REX and the poor guy firing it may have a flinch for life (smile)
The second link is the source page which actually does not have this video... but many others from the same operation.... also check out the one titled norwiegan hero #1 to see how someone else handles this pea shooter
