guys, I went to shoot some groups today and stood my target board up against a big rotten log i have used befor (there is a proper back stop behind it.) I saw a bullet hanging out of the back of the log which is over 14 inches thick. I pulled it out and had a look at it, it is a speer 6mm 105gr hot core spitzer.
It was nearly a perfect mushroom with very little jacket separation. i got home and wieghed it..... it was just over 95 grains!!! it was just under 14mm wide accross the mushroom.
