I have a Sendero in .300 Win Mag. I have shot Barnes TSX, Nosler Accubond, Hornady Superperformance Interbond, all 180 Gr...and the winner is... Remington Core Lokt....huh???
I had bought the stuff just to break in my barrel, but it has consistently out shot everything else, even out to 700 yards. Go figure??? My gun is a cheap date. haha. Plus it is something you can find at any sporting good store (especially in 180 gr.). I will consistently get .5 MOA groups out of it. Does the trick for my level of expertise (which isnt saying much. haha)
