I shoot the Scorpion .50 caliber but .451 caliber bullet in the 260 grain size. I shoot both the funnel nose and the PT Scorpion. These are very accurate out of my rifles with 100 grains of powder. Also I found that in my Knight Disc with 90 grains of BlackHorn 209 they are very accurate. I have not taken game with them. I did do the standard wet paper test which only tells me what they do in wet paper.. but I got excellent penetration and expansion. I see no reason these will not perform very well for you. Good luck.
