I actually shot a cinder block at 1000 yards too the same day, but my camera got too hot and crapped out. At 1000 yards the Berger OTM's barely put a 1/4" dent in the thing. I shot it about 5 times too because I was expecting to see that thing crumble in my scope. Now I'm looking into some good brass solids that I know will do the job at 1000 yards. The Berger's just don't cut it for hard targets.
Another good video from you! Thanks!
I am really intersted in the .338 Lapua Magnum. Your videos keep my interest up.
