I am seating the SST's touching the lands. Of course the result is different in every rifle, but it works well in mine. They are longer than magazine length so I basically have a single shot Rem 700, but that is where they are most accurate in my rifle.
I have concerns about shooting game heavier than medium sized < 200lbs. with this bullet as well. At the velocities of the Weatherby and RUM, I think controlled expansion goes out the window at closer ranges. I chose to try this bullet because I think it will perform better at longer ranges when velocity drops off. One field where I hunt is over 700 yards from end to end. At those distances, I'm hoping fragmentation will be less.
