For anyone running a Criterion/McGowan/Shilen prefit in 6.5x47 how does it do with the 140gr bullets?

It seems most 6.5x47 chambers are throated for the 120/130gr bullets.

I'd like to run a 26" medium to heavy varmint contour on a large shank and will want to focus on the 140s.

Is anyone running them?

How are they doing?
