wolf ammo is already sealed on both ends.

Most american production ammo and normally reloads are not sealed on the ends, the reloads have a better chance of getting moisture in the case if unsealed.... It's a added procedure if you want somewhat of a ultimate ammo to put up type of thing....

Tha ammo can and silica gel is probally just fine.... Although keep in mind that the silica gel is there to suck the moisture that may form in the can out of it, once it gets full of whatever moisture that is in the can it won't do the job any longer so they should be replaced or repacked from time to time, of course were talking a long time though. The ammo can will keep moisture amoung other things out of the ammo in it but it won't keep all of the moisture out of it as moisture forms from condensation and therefore if the ammo can changes between drastic temperatures it will produce moisture from the air which was in the can when you closed it....

The primer pocket and the primer are seperate pieces, as the primer is pressed into the primer pocket of the case, so that means that there is always the chance that something can seep into the case at this point. WD40 isn't just oil, it is a oil compound that is designed to lubricate metals, and bond to thier surfaces, along with the ability to break down rust and crud so it will seep into the primer pockets by design, once there it will make the priming agent useless. It will also adhear to the casing and stay there, which will effect function of your firearms depending on whatever grit or temperature you break this ammo out in and have to use it.....
