This was surprising, a marble at 150 psi made it snow Yellow Pages.

Almost a perfect hole in the cover and the rebound at about 0.4" in, shot the holes into the air.

I love phone book shots because of the confetti effect. Interesting how attorney's universally slime the backs of them with their advertising.

They're blue! I didn't know about that confetti effect, depends on your projectile I suppose.

Nice damage :)

Been thanked: 1 time

I found that old magazines and newspapers are great as bullet catchers

Best bullet catchers are either thick carpet hung up or a pile of rags, but i am sure news paper would work well too.

I rolled a half of a 3x5 index card around a plumb bob and used hot glue to hold it.

The shot was at 100 psi and it completely penetrated the 1" yellow page book.


Amazing penetration at only 100 psi pushing a 70 grain nail dart.

i made it in less than 2 minutes.

Straight flight.

I combined the rolled paper and the molded milk bottle techniques.
