I own a 378 Weatherby Mag in a Weatherby MKV deluxe rifle, I am trying to work up an accurate load using Barnes 270gr TSX bullets. I measured overal lenth with a sinclair overal length tool and if I seat bullets so they will just fit into the magazine, my rifle has 0.585" freebore. This is over 1/2 inch!!!
Is this excessive or normal for a factory weatherby rifle barrel?
I have measured this with several different bullets and they all come up with simular results. Thanks for any info..
