If I already didn’t own a6x47 Lapua, I would be trying one.As much as I like about the Dasher I'm thinking I may like the GT better. With the GT I can use my AICS mags without modification. The GT can obtain and beat Dasher velocities with a bit less pressure=Posible longer case life.
I'm kind of in the same boat. My gunsmith claims 6x47 feeds better than 6GT, but my limited experience is that the GT should be fine. Maybe I will build a GT someday...If I already didn’t own a6x47 Lapua, I would be trying one.
