Lately, i have been trying expansion test using various rounds. With outdated racks of ribs with 4 jugs behind them those where the best loads penetrating through the bone, flesh, and meat pack... others past through but either keyholed, barely expanded or fell apart. So I came up with those as the top .40 s&w rounds. Just top of the line compared to what i was shooting.
