Quoted:
I hate to break it to you,but they are not 00. More like #3 buck. The result is about like a low velocity 20 gauge buckshot load. 880 FPS so inferior to any normal length shotgun barrel. Cool idea though, shame it didn't work out well. |
This is an appropriate shotshell round:
 Shotgun Tank Round - XM1028 120mm Canister Tank Cartridge |

Here's some examples of the real thing. They are all the M576E1 variant, I never could figure out why the one on the left just says M576.
