Growing up we were always subjected to horror stories of guys trying to make FMJ's into soft points. Since the MJ is not really F, being open at the base, the story goes you would blow out the soft core and be left with the empty jacket in the bore. Then, you chamber the next round.... (cue ominous music)

I remember as a kid seeing an article in one of the shooting magazines about the .303 in Australia, entitled "The Ruin of the 'Roo".

And I'm surprised that no one, not even from Down Under, picked up on the Dinki Di dog food reference!
