Today I saw a fellow shooter with his ML shotgun. He was using a card wad over powder, then a cotton ball and another card wad, then shot then a card wad. Same card wads throughout the combo. However, what I was interested in was his cotton ball sandwich. I asked and he said it was just as good as a cushion wad but a lot cheaper. He then said he used one for 20 gauge but two cotton balls for 12 gauge (so apparently he has another gun). He also advised to only use real pure cotton. I'd never heard of using cotton balls. Does anyone do this or know of this?
