Re: 130 Gr Match King + 7mm STW for Whitetail?
A 130 SMK holds up to velocity, in flight at least. I've chronographed them at an ave. 3,671 in my 7mmRUM & a .522" 5 shot group.
I'd be a little leery of how they'd do at that speed into a heavy bone mass. It might be worth testing some into newsprint or gelatin after hammering through some scrap cow or deer bones or something. Just a thought.
