A friend of mine told me the chamber of my Anschutz-Savage 64 is sloppy(cut too deep) because a match bullet falls all the way into the chmber. He says the bullet should hit the rifling and have to be seated by the bolt. Is his statement true? This gun shoots about .625 inch ctc groups @50yd with Eley Tenex and Federal 911. Is this good for this rifle?
