It doesn't get any better than shooting a 30mm cannon. For proof, check out this video.
Is that old elephant gun you have been shooting just too small these days?
Why not try a 30mm cannon?! This little gem can be hauled behind your truck on its own trailer, and be quickly deployed on that unsuspecting target range.
This video shows this beast being shot with great impacts on the target backing berm, and the smiles must be contagious because everyone there was grinning ear-to-ear.
If we were shooting a 30mm cannon we would be smiling, too.
