Remember those three Sierra 300-grainers I was rolling around in my hand awhile back? Well, I stopped over and talked with the guy who gave them to me to see how he was doing with his Sako and .338 Lapua... Sorry to say...not so good! Seems he is now on his 5th Sako plastic stock! The previous 4 all broke in half at the pistol grip (and he was only using the Sierra 250's). He is also concerned because he has gone through 3 Leupold "Tactical" MK III scopes. Seems the crosshairs keep breaking. Is this a common experience by others?
