The 280 nosler looks about perfect for a big 7, but the 7-300 norma has its merits as well. Only down side is the custom action (from a $$$ standpoint) or PTG bolt, which ever route you go has its pitfalls and +'s. This is where a DTA would rock! Just really wish they would hit the market with a reliable double stack single feed mag.

I'm having Nate Dagley build me a 6x47 Lapua. It will be my LR yote gun. He already has my Benchmark fluted #5 at his shop. I still need to decide if I want it cut at 25 or 26.
