finnlight wsm pressure problems on extraction

Greetings, i was looking for a little insight prior to sending rifle off for repairs if needed. 6 mths plus ago i purchased a Finnlight .270wsm . I just now got around to shooting it, (i know....) Anyway, during barrel break in only 7 shots fired so far, shooting Fed prem ammo, the rounds feed smoothly, however after the shot they are extremly difficult extract- opening the bolt takes some umph! it opens just not like i believe it should and then the extractors mar the base of the casing. iam only guessing that this is a headspace issue?

This exact problem happend with a model 700 .300wsm i bought a few years back, i tried 3 differents brands of ammo, all had same issue, so i returned it and bought a .300 rum.. ANYWAY.. back to the finnlight.

thank you much!

    Without head space gauges you are only "guessing"! Is the fired case bulged or otherwise out of shape?

    Nope, no bulging or out of shape, case looks good other than base is mared, not the rim but the flat bottom of the case outside the primer pocket. But that of course is from the extractor.
