I have a CVA 50 cal. Optima V2 and it loves Traditions 250gr. Smackdown boat tails. They are made by Hornady. They come with EZ load 3 petal sabots, you can buy a pack of 15 or 30. They shoot under 1 1/2 minutes of angle at 100 & 200 yards, amazing! OH I put them down on top of two triple seven pre-formed pellets, I buy them at Dicks Sporting Goods. Have shot at three deer so far from 60 to about 95 yards, three shots three dead deer. All have dropped straight down in their tracks, the last one was the one at 95 yards. It was standing in some tall weeds on the side of a power line, all I had was a neck shot. When the smoke cleared I didn't see anything running, when I got up the hill to where I thought it was standing it laid there stone dead from a neck shot. I tried different CVA bullets because my gun was a CVA, they didn't group well for me. So I asked on different forums what guys were having the best accuracy with, Hornady and Barnes were the best two I bought both, went with the most accurate one. Good luck hunting and be safe.
