If you are talking about the lubed felt wads for for over powder I use them in my .50 Great Plains rifle and they work well for me. I use 85 grains of 3f and the felt wad and a 370 maxie or a 410 great plains and get 1 to 2 inch gropes at 75 to 100 yards. The loade works good on deer but I think that its a little lihgt for elk.
