Good idea or starting point.
Also try a different box /brand of ammo.ive run into factory ammo that didn't want to fit in chamber of certain rifles.
It's no guarantee they all work together.also I wouldn't force bolt closed alot can wear down back of bolt lugs.takes awhile but definitely wouldn't force closed .can speed up ruining accuracy galling lugs
If one brand fits and another don't chunk the bad brand and try something else.go from there
