Hal,
It might also guarantee that you never see another golfer while you are on the course!!! Since you mentioned the 405's I now remember that I also tried them, but at the 70 or 75 yards at which I was shooting them. 50 yards with the heavier bullets may have produced more favorable results for me as they obviously did for you. As to weight, I think that around 35 grainers would be all I would probably ever need to shoot at hogs, etc here in the states. I will probably only ever get to an African safari in my dreams now or living vicariously through others I know who have gone and continue to go. Happy hunting!! Also, let us know about your golf game with the 45-70 club!!
