I will throw my 2 cents worth in. With a lot of magazines being self indexing, and somewhat closed up, I dont like using an oily or waxy product because of ending up having to clean the insides of the mags someday. But I do like to use a lube. I also like Hornady one shot case lube. It dries to a non sticky lube in seconds, and I have not found a barrel yet that shot different when using it. But they sure clean up easy. I just pour a small tin of pellets on a paper plate and make sure they are all laying on their sides. Then I spray them lightly ,then roll them around a little to get a different angle on them and spray them again. It sure has worked well for me .
