I took the sides off an old computer
case that I was using as a convenient target stand and thought "Hey,
wouldn't it be cool if I put a round of 00 buckshot through one side of
the case, then blast a load of 7.5 birdshot on the other side and
see how they both do". Well a picture is worth a 1000 words.
As you can plainly see, birdshot is meant for birds. It
doesn't do much to old computers, or the local crackhead breaking into
your house. When you need to ventilate a scumbag, leave the
birdshot in your range bag and load up with 00 buckshot.
