You'll get more grunt out of the nosler about 100fps if it's done with a custom reamer the sammi spec is very short and holds it back. also I'd tap them both out at 230gns 245 bergers is 300norma imp territory. 215 bergers is a popular favourite . 225 eldm is brutal. I'm not sure what factory offerings youd get in the nosler though and itd be saami spec which really clips its heals. Theirs a fair bit of 300 prc factory offerings now both ammo and rifles feel free to PM for anymore info
