My seven also likes the 160gn Woodleighs but not using H4831sc. I've found that H4350 works best on all bullet weights from 140 to 160 and that's about the only weights I shoot now. Although I did give the Hornady Interlock 154gn a run, and they did Ok. I only shoot 3 round groups in my hunting rifles, because A) the barrel gets too hot, and B) if you haven't killed it in 3 shots maybe hunting is not for you.
