[QUOTE="coyotezapper, post: 2100020, member: 20438"] Weatherbys have a mile of freebore and this reduces peak pressure curve and makes it more forgiving. On the opposite end a minimum spec reamer will have minimal freebore and will pressure up earlier and quicker. If you send a piece of brass with a bullet seated to your desired length to a reamer maker the reamer will be cut to that spec and will have a limited freebore. My 330 Dakota reamer was cut for a 250 EH and the freebore is .060" A saami spec reamer is generally right in the middle. For my 28 Nosler builds I used a saami spec reamer with .188" freebore. So yes a load in a Weatherby would be way over pressured in a saami or min spec chamber. [/QUOTE]
