I used the 180gr tsx with my 300WSM. They shoot great well under 1 moa. Shot a cow elk with them at 240y. Pass through heart , good sxpansion, no blood outside of the animal, complete devastation inside. Couldn't of tracked the animal but wouldn't have needed to either. I've never seen such blood coagulation inside an animal. Anyway, drew Monroe so I'll be shootng them at a bruin hopefully soon!
