I used factory loads --- Winchester PP & Remington "Core-lokt" in 180 grain out my 30/06 for years. Never had a problem--- Last year I used some 180 grain "Hornady spire points" in some handloads for elk. They worked well on that bull. About a 150 yard shot. I'm not a fan of boat-tail bullets---- I like the old standard--flat base. I never have used the Nosler pt. The key is to hit'em in the boiler room with the 1st shot.
