I shoot the 240 grain HP 50 Cal Sabot. If I remember correctly the actual bullet itself is 44 cal. I shoot 100 grains (pellets). The gun has always shot very accurate and consistent with this round. This was the bullet that was recommended when I got the gun at a gun shop. Sounds like I need something else. Like I said before the bullet always killed just no blood trail. I was looking at one of the bullets this morning after my hunt and was thinking that maybe I was getting clean pass throughs and not much expansion from the bullet.
I know each round shoots differetly so i am not sure if I want to try to switch now mid season. I am not sure what I am going to do.
