308W Sako 123g game head factory ammo & pressure

[Thoburns]

Used these for a few years no issues, bought another 2 boxes and started to get stiff bolt and extractor shaving on the head. Went through the usual, deep clean, focused on throat etc. Tried it again today and the same results with the sako When I tried federal 150s zero pressure signs and shot a perfect 5 shot clover. Anyone else had pressure issues with the Sako 123s in 308w ? Just out of intetest as will be going on the Feds and returning the sako

No issues with the regarding any of the above, but I did change over to the hammerheads as it didn’t cause as much damage to carcasses. They were as accurate in my rifle.
