If all things being equal loading up 4 drams of BP, 1 1/4 oz of shot in a 10 gauge shell, does anyone know how much increase in pressure using Swiss powder compared to Goex?
I use Goex FFg for 10 and 12 gauges. Heard good things about Swiss but the lack of data information of how much change of pressure keeps me from loading them in my old guns.
