Typically lehigh combs fall forward from the high point which is further back, above the cheekpiece, than something like a Bucks rifle which has a straighter comb line. So with a lehigh, as the gun recoils backward and upward, at the same time your cheek may move forward slightly (depending upon how you shoot) and the comb movement is falling away as it moves upward. JMHO. they can still be cheek busters too if you don't have enough drop to begin with. A lot of the old ones that I've shouldered sure would have left me with a melon on my cheek.
