Nosler and Swift, as well as Hornady and Barnes make big game hunting bullets with the plastic tips on them. The swift bullets are big game bullets, as well as certain Hornady and Nosler. Now a 150gr Nosler ballistic tip loaded hot in a 300RUM, that would almost be like a varmint bullet. While the choice offered is fine, I personally like running 200gr loads in the 300RUM, and usually run Nosler.
