win 571

[smokemjoe]

I got a pound of Win. 571, Can that be loaded in 45 AR and 45 L.C. and if so how many grs. with 250 gr. cast. Thanks- Joe

Use HS7 data. It's the same thing.

Tried to look at some Vintage Winchester data pamphlets but no luck. Only data for 230 and 231.

I'm afraid 571 is too slow for either application, although if you can find HS7 data for either, it will work in a pinch.
