For those of us with limited depth to our pockets, the milk jugs filled with water have allowed us to compare one another's results. My own tests with FTX bullet tests showed the amount of penetration one could expect. While water isn't tissue or gelatin blocks, the tough skin of those multiple bottles were no cake walk for a bullet. In the case of the Barnes XPB bullets, I loaded the rounds down to simulate velocities out to 160 yds based upon initial muzzle velocity and their BC, in order to compare expansion at those ranges. The same could be done with the FTX and XTP Mag bullets. The ability to load down the rounds to simulate their predicted velocity would solve needing expert shot placement like that needed at the real distance. I still have a healthy number of those milk jugs stored in my garage and the better half has been bugging me to use them or lose them. I could put them to use and run a couple of iterations of the 250 FTX vs 240 XTP Mag at 100 yds but the starting muzzle velocity would be limited by my AR platform. We all know that you can jack them up appreciably in a bolt action. Can't help you there. I've been looking for a "calling" to go back to the range with my 450b. Tomorrow, I'll get a count of how many bottles I have in the garage and see if there are enough for a run at each bullet.
