I used an Omega for many years... I shot to primary bullets out of it both Noslers a .451-260 grain and .458-300 grain. Both bullets were powered by 110 grains of T7 or sub BH for the T7 not much difference in FPS and were awesome bullets. I used the regular HPH-24 sabot and the MMP HPH .458-50 Orange sabot. No problem loding these at all, but it was on older Omega - the new Omegas are suppose to have a tighter barrel. No matter I would still run a 100 strokes of JB's bore paste through the barrel.
Good luck
