Alzgarvin, I got my 2 sleeves and solid yesterday and tried it out. I didn't hit the center of the slug and ended up cracking the side of the slug and breaking one of the locks. I'm going to order the pre-made rounds and try it that way. Also, when I put the drill bit to the slug to dril it, the slug fell down about a 1/16th of an inch because of the pressure. Oh well, you always break the first one. What do you recommend to cut of the excess outer sleeve once you install it and how far up does the new inner sleeve stick up above the ball when you install a new one? I don't have much pitch, 1/8 reverse and 1/8 left pitch (righty). Other than that, I like it so far and I like it since there is not much slop when you have the sleeve inside compared to like the Thoms Thumb insert. Anything you can give for advice would help.
