2900 fps with an '06 and 180 gr. bullets ? What's that ? The Federal HE load out of a 26 inch barrel ?
Be interesting to see how well that ammo handles 90 degree temperatures.
I understand the .375-06 has never been popular due to the lack of shoulder of the case.
You'd probably be better off using the .350 RM or the .284 Win cases. E
