I plan on using 777 and hornady ball. If i cant find any wonder wads i'm guesing crisco is the way to go to prevent chain fire/flash over??
That oughtta do it. I usually use Bore Butter, but Crisco will work fine. One little trick with the Bore Butter is I have some 10cc syringes that I fill with Bore Butter, then use them to squirt some over the bullet. Crisco would be too solid for that.
At a Cowboy Action match a few years ago I used margarine. I didn't pack Bore Butter, thinkin' a vendor would have some at the range. WRONG! I went to the cook shack, lookin' for some Crisco. They didn't have any. So I got a stick of margarine from them. It worked fine, with one little drawback. Something in the margarine will leave non-removable little specks in your bluing.
