Deformation of the bullet bases have a far greater effect on accuracy than deformation on the nose.
Nevertheless, I'd try to return the ammo (most retailers won't take back ammo) and contact Winchester about it (send them the pic), especially with respect to the sloppy crimps.
The trouble is, if you return it, they'll probably just stick it back on the shelf so the next customer gets it.
The bad crimping can't help accuracy, either, since the cases now have varying internal volume. But worse than that, the rightmost one in the pic looks like the bullet might get stuck in the rifling on feeding. Bad news, especially with an autoloader.
NOTE:
I would be fairly certain that it didn't leave the Winchester factory that way, though. It somehow looks like someone deliberately tampered with the ammo. I can't imagine a mere droppage damaging the noses AND pulling the bullets out that far, both at the same time.
I hate to sound paranoid, but that kind of nose deformation makes it look like the bullets were pulled with an inertial bullet puller, which can damage the noses, and then inexpertly replaced in the cartridges for some reason.
I won't speculate on why this might be, but I do know that enemy ammuniton has been sabotaged by reloading their captured ammunition with tetryl or other high explosives. This was done with a little more finesse, however.
Don't shoot it.
This follows the general principle that if anything at all is funky about ammunition, the arm, or a particular shot, stop and thoroughly investigate immediately.
