I'm curious what gun you use? I've used a 4 5/8" Black Hawk 41 in the past with the same load almost. It's best group is @5" at 25 yards. I discovered the twist won't handle the heavies. It did work on a couple of deer but it was very close. Love the 41 & hogs. The only time I get to hunt them is if I visit a friend in Texas.
