My Omega will shoot most bullets quite well, I used the 50/40 200gr Shock Wave and the 200gr 40 CAL[10mm] last year they did quite well on both deer and boar, In my opinion the best long range bullet available.
I have used the 250 gr and the 230 gr XTP with good sucess but this year I used the 250 Gold Dot it shoots very accurate out of my new Triump [the Omega and the System One are taking a break this year] and its preformance with a 100gr load of 777-FF has been very impressive this year. Check the post on Gold Dot for pic or the bullet that went through my buck and dropped him on the spot, it was a couple inches in the ground on the far side of the buck. I wanted to see what it looked like, so I hunted it up with my metal detector. Lee
