Daryl, this was before the 0175 wad was available. Mike, I don't load for the 20, but from the IMR handbook with a 2 3/4" shell - Rem primer, 17.5grs of 800X, and 7/8oz in a CB1078 wad you'll get 7900psi. If you load it in a 2 1/2' shell with only 3/4oz of shot your pressure will drop and it may fit with less shot. All you can do is try. There are any number of recipes that are in the 7000 range and by going to fiber wads from
www.circlefly.com you could make em fit in a 2 1/2" shell at lower pressures. Good luck - Paul
