Agree with tunofun on the solids: Brennekes are great, the rest don't rate!

I've used SSGs a few times years ago in the North Queensland 'J', never killed a pig dead with a single shot. I've also seen a couple of big Territory boars cop a load of SG and run off in the thick stuff never to be found.

They don't run away after a fair hit with a big blue-nose Woodleigh!
