I have tried both 245/295 gr Powerbelts in my Omega with nogreat results printed on paper. When I first got the Omega I started out with these bullets. I have taken 3 deer with this bullet but the blood trails were less than expectation.I have since converted to SW-250gr and will dabble in the Gold Dot 250gr/HCR sabotif they would ever get off back order status with Midsouth Ammo.
