Long Rifle - Match' chamber reamers.  (Drawing available at SAAMI.org)  This means that some ammunition will cause the bolt to close with resistance and that you may have difficulty removing unfired rounds from the chamber. The match chamber will cause the bullet to be pushed into the rifling. Be sure to use extreme caution and always keep the barrel pointed in a safe direction while chambering or removing a live round.
