Any people with copper barrels

[jsefcik]

If you have a copper barrel and you are using 1/2 inch, I found a new ammo you can use and fits great =)

Use double A batteries, my little brother found out by just trying it. He was able to launch them things out of site. =)

I had better performance shooting them out of a 2.5 inch barrel in a sabot. They flatten much more when shot against a steel plate. The acceleration is much higher.

Is that styrofoam? With the battery in the middle ?

Tech - That's impressive battery pancake, did you use your QDV to achieve this? if so what was the operating pressure?

... and PET bottle support, otherwise the foam will collapse.

@ jackass, what PET bottle support, it looks clearly like styrofoam
