I just got my 22-250 built and went to the range today for sight in and I'm having a little problem. The extractor will not hold on the case and it just pulls the brass back a little then it falls free. If really "whip" the bolt back about 6 out of 10 will extract/eject but I don't run my bolt guns that way. Funny thing is this action functioned perfectly while in use as a 6.5 Creedmmor never failing to extract every round. Could it be the 22-250 case?
