I've known for a while that PT&G offers a piloted counterbore for cutting the .705 bolt nose recess in Rem 700 barrels, and have contemplated acquiring a couple.

Looking at them on PT&Gs web site I see that they offer a straight and stepped version. Can someone explain the difference?

I never thought I'd grow up to be a grumpy old man, but I did, and I'm killin' it.
