I was out last night practicing off hand with my Tikka 7-08 and my 150 grain handloads with Sierra Game Kings. I was down to my last 2 rounds and decided to 'ring' the metal upright that the plywood backer is mounted to. This steel upright is made of railroad track buried into the ground with the flat( bottom) facing the firing line. I picked a spot above the edge of the plywood backer and squeezed off a shot. I heard the 'clang" of a hit but couldn't see any splash from the lead. I fired again and got the same results. When I walked down to retrieve my targets I looked to see where I'd hit. I still couldn't see the splash marks until i started to move away from the rail and I noticed that two of the holes in the rail -which are usually the product of FMJ so I didn't initially pay attention to them- had bright silvery metal painted around their interior. This was left of center but the bullets still blew through a half-inch and better of steel leaving a hole I could stick my pinky finger through.
And I'm going to be using these on deer tomorrow. I'll let you know how they worked.~Muir
