Congrats, showever got you that Omega for Christmas did you a great service. Follow the advice that has been given by Indiana Smokepole and Cayugad and you'll be happy. I currently shoot the Barnes 245gr Spitfire with either two 50g T7 pellets or 90g loose T7 FFG. I plan to get me some crush rib sabots to try with some Barnes Expanders 250gr and maybe some Speer Gold Dots 250gr, I may also try some bonded 250 shockwaves. The regular 250gr shockwaves shoot great out of my gun.The only thing I would suggest in addition to what has already been said is that if you go with the 250 shockwaves get the bonded ones.
