Re: 1903A3 reloading trouble
[QUOTE]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.
Whether or not their trimmed lengths compliment one another, are they trimmed to the proper length for the chamber? Have you compared overall case length of the trimmed cases with the length of the factory loads that will chamber?
What FL die are you using. Does it bump the shoulder back enough? Are you running the case into the FL sizing die far enough?
How are you measuring OAL. Is it base to bullet tip or base to ogive? What are you using to take that measurement?
I have a great woman, fantastic kids, a warm place to sleep and an accurate rifle. Life is good ..............
