I went out the other day and was mucking around with the consept of weighted projectiles? I filled a tennis ball cut in half with rocks and had a go........ Home made shot gun anyone? after a few shots and having a good chuckel i desided to fill a Tooheys extra dry bottel with sand. a beer bottle basicly for those who live outside Oz. Now ive seen sum scary results with TED bottles and ill show u what empty ones do then what sand filled ones do...... Hope you Like

I tried the weighted tennis ball idea. I filled a tennis ball with a bunch of lead. It put a clean hole through an inch of plywood. Weighted projectiles are like freakin AP rounds.

and uhhh. btw
those tennis balls were two inch ones instead of 2.5".

Ouch Dude!! yeah im just stuffing around with it at the moment. I got my 1.5 barrel riffled and now im about to do the same with my 1m. My 1m is a shot version and is more compact and makes for twice the bang. Im gunna go see what it can do at shot range. coz all my projectiles are long gorn when i go looking for them.

My favorite AP rounds are Pycrete. It is really freakin strong and I can put that through 2, 1" boards. That stuff is awsome. You should try that

Just take a 4" section of pipe the same as your barrel, Put (not Glue) an end cap on it. Fill it to the top with sawdust. (Don't compress the sawdust down) Fill it up with water and stick it in the freezer for like 8 hours.

Take it out. Take the end cap off. Beat the pycrete out.

And you now have a super awsome AP round

And Pycrete just sounds cool too.
