Let me tell a short story -- Many years ago when I was young, to many to count. I was cleaning my fathers 30'06. I took it apart, stock off, scope off, bolt out, cleaned trigger, polished, oiled lightly, cleaned barrel, inside and out. oiled lightly, cleaned bolt and firing pin, repaced. Put stock back on and scope. I held the rifle up to my eye, but not holding it tight, and aimed at a paper flower in my dad's basement. Their was a cinderblock wall behind the flower, I pulled the trigger. The next thing I remember, was cleaning blood off by forehead, again I wasn't holding the rifle tight at all. There was white dust in the air. A 30 cal. hole in the paper flower, and a 2" hole in the cinderblock.
To this day I don't remember putting 5 rounds in the rifle, 4 in the mag, one in the chamber. It was very lulcky that know body else around. I fixed the whole before by parents got home and they never knew, until I told them, about 30yrs later. I think about it every time I pick up a weapon. That is nearly every day. I reload, shoot and hunt a great deal, but never forget that day......
