User06, as I just stated in another thread, I really like the 12 gauge version of the Winchester Platinum tips in my H & R Ultra slug hunter. I have taken many deer with this rifle, the last whitetail was at an honest 150 yards as per Leica rangefinder. The 20 guage version was not available when I purchased this rifle a few years ago, or I would have opted for it over the 12 gauge. They both shoot similar trajectories, the 20 just puts a lot less into your shoulder. I don't casually pull the trigger on the 12 guage, want to be ready. Definately recommend the Winchester Platinum tips. Just remember, not quite as fast as the Partition Golds, but they also kick you a little less.
