I've got/had a Sendero in 7mm Rem Mag and it loved 180gr Berger Classic Hunters. Tore it down though and I'm in the final stages of rebuilding it. I've accurized the action and re-barrel to a Jury 1-8 twist to try shooting the 195 Elite Hunters.
Anyway, here's a group I shot with it before the rebuild when I first got it. Not too shabby for a factory rifle. This was with the 180 Berger Classic's. I haven't had a rifle yet that didn't shoot Berger's well.
