99% of blow ups are due to user error. Poor cleaning, incorrect loading, incorrect prep between shots, etc. A lot of new guys have no clue about the crud ring. I've personally helped folks that told me they always wondered why the ramrod always stuck and inch or more higher versus their first or second shot. They were actually shooting them that way, getting poor erratic accuracy from one shot to the next. They were blown away and down right scared [bleep] when I explained what was going on and what could have happened to them.

Its like the guy on the news that buys a brand new Lamborghini and wrecked it 2 miles down the road because he said he didn't need to take the recommended driving course/test.
