I'm getting great groups with Federal Classic [blue box] 130 grns.,but after reading the forums here many suggest 150grns.Now I'm hunting deer at modest ranges 40-150 yds. I want a load that drops 'em right now because I hunt public land and if they travel far someone else gets it.I never owned a .270 before so any suggestions ? Am I okay with the Federals ?I was thinking of maybe Rem 150 RN corelokts or 150 Feds.
