My very limited casting experience has been with 200 grain .45s but I want to start casting .38s. The mould I'm looking at is a Lee, double cavity that is described as a 158 Grain Tumble Lube 2 Ogive Radius. Attached is a photo of the bullet. I've never seen a cast bullet with all those small grease grooves and I have no idea what a "2 ogive radius" is. Does anyone use this style of bullet? Am I correct in assuming that his particular design is not good for pan lubing? I like the looks and am thinking of getting this mould but I only have experience with the 2 grease ring design.
