One time, a crew at a hunting camp in the Rocky Mountains had a small propane cylinder on the torch they used to light the wood in their camp cook-stove. They had a bottle that leaked and was stinking up the tent. Since they had brought along several spares, they decided to get rid of the offending cylinder. They set it atop the rotting remains of an old trapper's log shack, backed off about 50 yards and one guy took aim with his -06. Funny thing about a modern hunting bullet . . . it makes a small hole where it enters and a much larger one where it exits. Big hole provides an exit for expanding gas pushing liquid out of the hole. Said reaction tends to propel the tank towards the shooter. It also makes a very large cloud of gas vapor. Probably a good thing there was no flame to ignite the cloud. May have made for some singed eyebrows.

Think, think, think!
