Win. 571 / HS-7

… for your load data

The thing is, I have some very well preserved Win. 571 that I’d like to use. I also have a bunch of 12 ga Federal Gold Medal hulls. (I don’t want to throw my AA tubes out in the field, since my daughter-in-law shoots an auto.)

Does anyone have a 1 1/4  or  1 3/8  or even 1 1/2 oz load?
