I've been using the LLA mixed with JPW and mineral spirits. 45/45/10, heat the JPW in the microwave in a cup in a bowl of water sorta like a double broiler. Yes I'm single so I can get away with it..... Mix the JPW in with the LLA and mineral spirits and shake up the bottle. It's ready to go & yes it is much better when loading, there's no sticky bullets and it's helped a couple loads that was leading in a 357mag.
Now if I knew of a way to use castor bean oil like I used to use, say Klotz. I'd be hooked for sure.
