John, My results were from a Remington 700 in 350 Rem Mag with a 1:16 twist and a Ruger 77 350 Rem Mag with a 1:12 twist shooting into dry print at 100 yards.

The 35/280 SAF's shot with fine accuracy in the Rem 700 but they gave very poor penetration.
In fact, they gave the poorest penetration of any bullet tested which included 200's, 225's, and 250's.

The same 35/280 SAF out of the Ruger 77 gave far better penetration.

I might be missing something here, but it's my results.
