For some time ( and for some reason I don't remember, haha) I have been using JPW with LLA.
I can't follow the threads back far enough to find the original reason, but I wonder what it was.
I just got Dick Lee's new 2nd edition book. He says that LLA was someone else's idea that he liked so much that he bought it. And he never mentions JPW.
The LLA/JPW combo is messy, dries slow, accumulates in tumbling containers and puts chunks back in the mix, and accumulates in seating dies, driving me nuts with changing LOA.
I may have only purchased 2 or 3 bottles of LLA in the years I've been doing this. I have mostly used the bottles of lube that comes with the 12 or more die sets I have. I notice that old LLA gets thick and grainy and isn't as good.
Barring being persueaded to resume the orthodox LPW/LLA procedure, I am using JPW only for the other things it's great for, and I'm buying some new LLA and not trying to make the tumbling containers last for years anymore. And I am using LESS lube !
