Quite envious, the biggest round I've ever fired is about 6 100g sticks - about the size of the primmers in a quarry blast!
Was an erie place at night though, I recall stepping out of the weighbridge at about 2 in the morning for a smoke (when I used to). The wind was whilstling through the conveyors etc steel work & loose tin sheeting rattling - I was the only person there & it was a very quick smoke!
We inhabit an island made of coal, surrounded by a sea full of fish. How can we go wrong.......
