[QUOTE="LoneTraveler, post: 1179674, member: 77249"] All of the Weatherby factory chambering I have ever dealt with have a lot of free bore. To much free bore to load the bullet near the lands. Nosler loading data list starting load as 94.0 gr. of H1000 reloading data for 210 bullet. And Max load 98.0 gr. of H1000 with 225 Gr. bullets. Cartridge Overall Length 3.648" I have only seen 264 Win. Mag. cases with the weird sucked in dents in the case. These sucked in dents was caused back in the 1960's by a friend loading light loads of old Hodgdons 4831 Military surplus powder with 100 gr. bullets. There was black soot back to the shoulder just like your picture shows. Take a look at the chamber drawing for SAAMI 30 338 Weatherby specs. They show a distance of .569 from the front edge of the of the case neck to the actual rifling. This explains the bullet having so little depth in the case neck. I suggest you go back to Berger's loading data, using the primer and OAL they suggest. Good Luck and Be Safe. [/QUOTE]
