Throat too short in my .30-.378 ?
I just finished building a .30-.378 Weatherby, 34 in. Pac-nor 3/3 land groove barrel 1.1 in. muzzle, Hall single shot action. I did not want the typical Weatherby free bore but may have had the throat cut too short. This being a single shot rifle I am not too concerned about OAL, but the throat is so short when I tested seating depth with the OAL gauge (200 gr Accubonds) the bullet is so deep in the case that the boatail extends below the shoulder appox 1/8 in. This appear to be taking up a considerable amount of case capacity ?? I plan on shooting Berger 210's-Sierra 220's so the problem will probably be worse with the longer bullet.
I did not put a 34. barrel on the .30-.378 only to turn around and cripple its potential buy having a throat that is too short.
Am I killing some velocity potential with this short throat ?
