Tahquamenon,

What granualation of Swiss are you using and what caliber and loads do you use. I bought some Swiss 2f to try out in my 1/28 twist Green Mountain barrel, with 300 and 250 grain Hornady xtp's. I have not shot much of it yet and probably won't complete my testing of it until spring weather. Are you using 3f? in a .50 cal. with sabots?
