I have an Omega with a real tight barrel and can only load SST bullets by throwing away the sabot that comes with them and replacing it with a short Harvester sabot. I also use the 295gr. aerotip powerbelt as a follow up shot to the 300gr. SST and find the point of impact within an inch at 100 yards using the same 90gr. load of Black Mag'3. I had to use the follow up shot this last year on a big elk cow and even though the SST would have put her down eventually I was not sure so I sent the second bullet which did stop her. I hunt alone and do not want the elk to run very far or get too far from an easy access place as I do not want to have to pack out pieces. So far I have been lucky on the three that I have shot. This last one was the worst and required dragging and towing about 200 yards to get to where I could get a rope on her from my Samurai. Elk do not drag well. (I was lucky and had another guy with me on this one).
