It's OK; at <300Y, most bullets will do. As others noted, the 115 Berger is a bad arse pill.Don't know the barrel twist. I'll check. It's a Ruger M77 MK II.
I was a long-time NBT user before I transitioned to Berger. Yes, they will do good as well. But my preference is Berger.Any experience with Nosler Ballistic Tips?
