So...I've been casting for about a decade now and have all the molds I NEED for my guns and a Lyman 4500 lubesizer. I've been researching this whole PC thing and wondering if it's worth switching methods for lube/leading prevention if I already have what I need and is working well. I'm shooting cast out of a .357 Max TC Encore 18" barrel, Smith K38, .260 Rem, and .30-40 Krag single-shot. All use Lotak Hard for lube and I have great results. Am I missing out on something by NOT using PC?
