I was out yesterday shooting my steel gong at 200 yards with both my 308 and 223. The 20 inch 308 was giving devistating shock hits on my gong compared to the 223. My gong was a mild steel plate 6"X6" and 1" thick both the rounds where only leaving small dimples on the steel plate.
The 223 would move it but the the 308 would flip it backwards and almost overtop.
I drove my truck down to the 200 yard area and then walked another 200 yards in the deeper snow where I coudln't drive anymore to set my secondary gong at 400 yards its a bit bigger 7"x8"x 5/8" thick I chose this one for 600+ yards but figured it would try it at 400 because I didnt really want to treck thru 200 more yards of snow. By the time I got back and it was getting dark I fired one shot at the 400 yard gong... it was a hit but barely moved it so I packed up and went inside.
Next weekend I am going to play with the 308 at 400 yards and see what the power is like, I will also coronograph the rounds once I get them loaded up in some new brass. So I can work out a drop table to start playing at longer distances.
So far my best at 100, -7degrees, very little wind
