I know it is needed for tubular fed magazines and box magazines in semi-auto/full-auto rifles.
Is it necessary in a bolt gun with a box magazine?

Vote 3, no crimping on bolt gun ammo.
357 Mag, 44Mag with hot loads in revolver yes but none on bolt guns. I have found no need to crimp on gas guns either with correct bullet tension. On a bolt gun for rapid fire I will run about .0015 for bullet tension up to .0003" oversize expander for long range ammo which gives about .0005 bullet grip for single round loading.

Hell, IDK!
Load up a magazine with rounds made to a measured OAL. Feed/fire them all, and hold off firing the last one. Measure the OAL. If it's changed, crimp. At least you'll <span style="font-style: italic">know</span>. Asking for advice on the Internet for this sort of stuff is like making love over the Internet. Doesn't work.

I stopped bullets without a cannulure a whiles back, under the advice of brian enos. As long as you have enough neck tension, the crimping process is just an added step that can only screw up a nicely loaded round, not help it. In all, I don't think that you will be able to see much difference either way, as long as the crimping process is not botched.
