I used to reload Federal Paper with a 12SO wad and PB powder. It was a beautiful low pressure charge that pattern great and destroyed targets on the skeet range. I think the pressures were in the low 5,000 psi range. These were 7/8 and 1 oz loads. An added bonus was the amazing smell of PB with paper. It brought me back to the 1960's when plastic hulls were new and you get paper target loads at a very low price.
