VAnimrod,
I thought about heavy cast bullets and agree with your accessment. The 30" Badger barrel utilized by Browning and Miroku in Japan was made for that application. This used BPCR came with a spread sheet of cast bullet loads the previous owner had worked up for this gun. And some were about as accurate as the Barnes 250 TSX load. There's no way I would shoot at a deer beyond 300 yds with this rig and the Barnes bullets are more destructive than a plain lead projectile. Cast lead bullets in a 45-70 can't be pushed to 2,500 fps and the trajectory wouldn't perfectly correlate with the Ballistic reticle like this load does.
