Morgan,
My son and I watched the “Great Glock Watermelon Shoot” DVD Sunday afternoon.  What a hoot! 
 
He and I went out last month with watermelons and cantaloupes.  My first shot was at a watermelon from about 10 feet with my Glock 29 loaded up with Double Tap hollow points.  Definitely a 3-star result!  Surprisingly, my Ruger Mini-14 in 6.8mm SPC got the same results at 100 yards, but I can’t carry that thing around on my hip.
 
Have a great day!
Rob
