Don’t trust cabelas putting on your mounts and scope. Get the Wheeler torque driver next time it’s on sale and so your own mounts. It sounds like you can shoot so I’d check scope/mounts first for sure.
Also, that Herters ammo is complete and utter garbage. I’ve shot the 150 and 180 grain stuff in 3 different 308s that shoot easy under MOA for me and the stuff grouped 2-4 inches! This was even in a Tikka T3X!
I’ve owned 4 Weatherby vanguards over the years and every one shot sub MOA with the right loads. Never would shoot any loads worse than 1.5 inch 100 yard groups on average.
I never have relieved the barrel pressure on any of them. That would be a last resort for me if I tried everything else.
Good luck
