take the "complete powder burn" with a grain of salt.

I have a similar setup, grt claims the same thing (quick load does not) and its a flamethrower.

You won't need to wait till nighttime with this setup. And yes i have tried a similar setup.

Also do not use it when there is a fire risk, the last thing we need is a hunter setting some public...

The pyrotechnics are going to be spectacular!

For a really short barrel I would go with a heavy, and potentially softer bullet.

More efficient under the circumstances.
