25-06 should not have an issue. They will not make you ship it to finland. Only MD.

I would first identify where it catches. Might just be catching on the detach mag. Which I have a feeling where it is catching.

Is is only one brand of ammo? Reason I ask is, on my STW which is also a 75, if I cycle slow, it might catch and only if I didn't deburr my brass. It catches sometimes, on the brass mouth. If I deburr, it I never see the issue.
