Because on top of two 50 grain pyrodex pellets and using a CCI 209 primer the 250 gr shockwaves shoot like this out of my T/C Omega. First shot at 100 yards to make sure it was still zeroed.
I was mainly there to help a buddy sight in his muzzleloader so I didn't shoot much more but I did take a few follow up shots at some other targets just to confirm. The last shot being at a full sized cardboard deer target. Aimed at the edge of the top of the heart and cut that line into from 100 yards.
I have had a love hate relationship with shockwaves when it comes to blood trails (sometimes good, sometimes barely there) and how far deer have occasionally run after the shot. But it is hard to leave a bullet that shoots this well from my gun.
