Actually I wasn't attempting any kind of a test. I just wanted to "catch" a projectile that had been fired from the gun and the penetration issue was a by product. I was trying to see how much mushrooming I would get.
check out exhibit one, the bullet that was shot into the bale only....
Essentially it is the "pristine" bullet but without the controversy. I could shoot this one over; essentially no damage though it travelled at least 3/4 of the way through a three foot (or so) heavy alfalfabale...
Exhibit no. 2. Styrofoam, pressboard, bale...
Though the photos are less than desirable you can see that the petals are starting to open, some of the lead interior is exposed, but the plastic tip is very much in tact, even after travelling the entire length of the bale and sticking side ways in the wood backstop.
Exhibit no. 3. Styrofoam, gallon jug of water, pressboard, and then the bale....
Basically a flat piece of lead with the copper jacket peeled almost all the way back. It now weighs in at 170 grains. The photo isn't very good because the right side is really exposed lead and is grey but you almost need an imagination to see it in the photo because of the blurr and reflected light.
I killed one last year at 143 yards...went through both shoulders and he dropped...
After seeing these results I can see where that is a real probability...
