I have the exact opposite trouble as Rackattack. My ACC 3-49 inserts seem to shallow.

I didn' t really notice much of a problem until this spring. I shoot a 75 grain field tip and 75 grain Rocket wolverines, and they go in just fine. However, I recently wanted to see what a 100 grain head would do, so I tried to screw in a 100 grain field tip. It lacks seating against the insert by about 1/8" . For chits and giggles, I tried to screw on a 75 grain titanium steelforce, same size as the 100 grain but made of a lighter material. Same problem, won' t fully seat.

Basically it appears the insert depth before the threads are engaged is too short. Is this a common problem with these inserts? Am I " doomed" to shoot Rocket heads the rest of my life? Did I get defective inserts?
