Eeek...I just googled a Savage in .338 Lapua...holee schidt...it only weighs 9#. If it doesn't kill you it'll kill the scope for sure.
Oh wait, I was looking at the wrong specs...it's 12#...still?
I've shot them, they are not that bad. Especially when using the brake. One of my buddies has one, and it easily shoots sub moa for 5 shots. He's running an old Vortex Viper HST on it. It seems to be holding up, but not what I'd suggest. I'd probably look for something like a fixed power SWFA SS, and call it a day, if I only had a $500.00 budget.
