I noticed when closing the bolt it felt like it bottomed out as it should but, when I pushed down a little harder it went down just a slight bit more. if I pushed forward on the bolt while closing, it bottomed out just fine . I got out a 1/4" allen wrench loosened the bolt handle retaining srcew worked it back and forth a few times then tightened it back as tight as I could by hand holding bolt handle. Now, it seems much harder to close the bolt now on an empty chamber then it did before but, the handle goes all the way down like it should now. The hex bolt was hard to un,tighten originally but, is it possible I may have over tightened it when I re,tightened? Thanks!
