I use Rem 180gr corelokts, why I use these is that they shoot real well from my rifle and my father shot them and it rubbed off on me. They shoot about 11/2 inch groups @ 100yds and where I hunt any shot over 200 yds is very rare. A few years ago a shot a 140lb doe, I hit it just behind the ribs and the bullet went foreward and ended up in the offside front leg. The doe went about 20 yds, when I recovered the bullet it had mushroomed amd looked like it was from an ad. I trust that round so why change.
