Ok,

Perhaps I jumped the gun. Both cartridges with the appropriate load and bullet, say the 45-70 Garret Hammerhead and a '06 with a woodleigh 220 RN are awesome killers.

I'll agree that a P+ 45-70 is way better stopper then the '06.

My gut felling is that a man will find a 30-06 double a lot more versatile (in the long run) than a 45-70. But my head says most will opt for the 45-70 big bore.

BTW, I'm a huge fan of the 458. I have a 1978 H1 tropical in .458 mag, a 500-450 DR, .45 long colt BlackHawk and a .45 Glock.
