Lazy,
At 29.4 are you getting that crunching feel when seating a bullet?
I figure up to 103% of available case space is OK given space being filled with powder (especially extruded powder) is more 'elastic' than fixed. We manage this by using drop tubes and vibrating the case to settle powder levels lower and fit more in. But at some point it becomes fixed and you start to break up stick powder and change its burning profile.
I use 28.5/8208 with the 107SMK, 58mm OAL but have wondered about going a little more. It is a really accurate bullet and load.
