Uber Destructive.

I'm sure that by now, the vast majority of you have seen the flared pvc rockets featured on a number of spudding sites. I have made a few of them recently, and they make for solid ammuntion. However, I have found that using Quickcrete, or some other type of "just add water" concrete mix can be devastating.
Just pour the powder into the end of the body of the rocket (about half an inch) and pour the reccommended amout of water for the brand you are using, mix it with a screwdriver or something, and let it cure for a couple hours.
I've put them through doors like nothing. (ones that are not still attached to houses ) Have fun kids.

A concrete bullet? Sounds devastating. Could you add some pictures of your shots and of the damage?

[WOW!!]

I've heard that those things are destructive enough by themselves. I've never made any but maybe I'll try some if they have even more demolition potential. I'd love to see those holy doors.

How to build PVC rockets

My favorite way to build ammo is to basically build the rockets above, but without flaring the end, just filling them with sand or water and capping off that end as well. If they dont fit snugly, i add a layer of duct tape to either side until they do. Takes about 5 minutes and are easy and just as cheap.
