I have an Omega and I am one of the guys that switch from sabots to Powerbelts. I shot Hornady SST bullets in Harvester sabots (my barrel is so tight the Hornady sabots won't load without extreme pressure on the ram rod). I checked both fouled barrel and clean barrel with both bullets and the 300gr. hornady hits within less than an inch of the 295gr. powerbelt aero tip at 100 yards so I can interchange them. I just shot an elk this year with the first shot the sst and the second running shot with the 295gr. Powerbelt. Both hit about where I planned and the elk went down. The first missed one lung so I had to do the second. Four holes in an Elk is usually enough.
