Wow. I thought 3200 with those 105's was speedy. That's another level of flat shooting there. Have you got any of the 110gr Sierras worked up yet?
The 110 Sierra was the bullet of choice that I originally was focused on, which is why I went with a 7.25" twist & the reamer was set for.
Turns out, I struggled with huge runout from the beginning that took a while to diagnose, so I may have to revisit them again.
