Thanks John. Reason I'm asking I picked up a very nice pre-64 Featherweight in (gay) 270 made in 57 with an old Leupold 4X and some four boxes of new 130 PPs that it plunks into tiny groups. I'd love to take it to Idaho and I don't have that much time (or desire at the moment) for load development with 130 Triple Shocks..of course
