I use the standard Super X of same weight. Not sure of benefit the Part. Gold may bring. ...might be better on bigger black bears than the Super X.
I shoot clover leafs at 50yrd w/open sites. Victims include a couple ground hogs 125yrds, 150+yrds. And the deer below last year's season. I dont think the slug expanded at all because the in/out holes were the same diameter. After it was hit, it fell like it was knocked down, then it jumped up and ran 30ft(into a brier patch

) and expired immediately.
Out hole on the left shoulder, was hit just behind the right front leg. Top of heart and path through lungs were mush.
