I was having problems with the XTP's that I have shot for several years. I switched to the Spitfire T EZ's. I shoot an Encore with 100 grains (pellets). Not sure how the bullet would shoot in my gun mid season I took it out and shot one round at 50 yards. It shot about 3 1/2 inches high, dead center. I moved back to 100 yards and the second hole was just touching the bottom of the first hole, again dead center. Since then I shot two does with this bullet and both went less then 50 yards and died. Both left a good blood trail (the main reason I switched). Here is the bullet that I recovered from the second doe I got last Sunday. I shot her at about 70 yards hitting her just behind the left shoulder. The bullet was found between the meat and the hide on the right side about half way back. ( the deer was angeling). As you can see in the picture the bullet preformed absolutely perfectly. The first kill was a pass through and I never found the bullet.
