It takes a licking and keeps on ticking!
Here are some photos sent to us by a "wildcatter" who relies on his PVM for accurate measurements. When you launch a .224 bullet from a necked down, Ackley improved .30-06 case, you can expect something to not go quite right. These photos show what happens when a .224 bullet decides to come apart in front of the light screens.
Doesn't look too bad.
Oops! A little more than first observed.
Let's look at the back side.
Remember, all of this was the result of the first shot!
Theshooter didn't realize that so much damage had been done until he finished the shooting session and he retrieved the light screens to put them away for the day. The PVM continued to perform flawlessly in spite of the damage inflicted by the first shot. Lesson learned: some bullets just don't enjoy being pushed to their physical limit. The PVM-08 still works but the light screens look a little "well used".
