Im having problems with my t3 222 at the moment. When the rifle is empty and a close the bolt it closes no problem at all and its very smooth. However when i put a round in the chamber the bolt is still very smooth going forward but gets very though when i try to close the bolt down as if the round isnt in far enough. I have tried sako prvi & federal ammo 50 & 55 grain in its doing this with them all. The accuracy is not effected and the gun still shoots perfect other than this. Has anyone suffered anything similar and can throw some light on the subject?
