Have a question and hope someone has the knowledge to help. I am trying to reload some 30-06 rounds for my 1903A3 sportster. I have grouped matching head stamps, full lengthen sized all brass, trimmed to within a couple thousands of each other and seated 168gr boat tail h.p. hornadays to the book and the bolt will not close. The over all length is .010 more than a factory Winchester load which chambers fine every time. The rifle has never had a problem with any factory loads I have asked it to shoot. If I seat the bullet so the case is the same overall length as the factory load, it will be to deep. Is this a big concern? Is it a chamber problem? All brass is within spec per hornaday handbook vol 2. Any help is greatly appreciated. Thanks in advance.
