I answer to your question

"I also have been under the impression that unless the bullet is crimped, the recoil from the firing of one
barrel could possibly dislodge the bullet from the case in the other (unfired) barrel."
Can one rely on uncrimped bullets in a 470 in a dangerous game situation? "

As I said in previous post, I generally DON'T Crimp ammo an that includes 465, 470 and 500
Nitro's in doubles.

HOWEVER, to reiterate, you do need to make sure that when you resize the case and / or necks of cases
that it does so in a way that it is tight enough to hold the bullets tight enough under recoil and running
around after game.

I don't recommend this for everyone but it works for me and I hunt with large calibres in DR's
and Bolt guns on a regular / yearly basis.

Hope this answers your question. Ask away if you have any more.
