If I might ask, why are you so obsessed with not seating anything but the boattail below the case neck?
My therapist and I are currently working on that...
I dunno, guess it's the way the round looks. And I have 3.6" to work with, why not use it...
Not a very good reason...
That's my story and I'm sticking to it...
Now, don't start messing with me, using facts and such like you always do...
