saw a you tube video where a guy put a 22 pellet gun pellet in his 22 rifle and pushed a nail gun 22 blank in behind it. he got very fast ft. per second and accuracy at 25 yards. i cant understand why the pellet didnt strip out and the nail gun cartridge didnt hurt the gun as it is so powerful. anybody ever see anyone do this? is it dangerous? seems to me it would be but what do i know?
