If targeting hand held/mounted guns, Shape Metal or Shape Plastic (depending on the actual materials) supported by Armoury/Engineer with Small Arms/Heavy Weaponry specialization depending on what is being altered (similar to how you'd use Architecture to make a stable building type construction). A normal failure on Armoury/Engineer would still make the munitions misfire, but not in a way that the caster intended. A critical failure on Armoury/Engineer would make the munitions behave in the worst way possible for the caster (ie. a bit of extra damage if used by enemies, destroyed weapons if used by allies).

Maybe in the interests of world peace all the magic users could get together and do a mass spell cast to negate or alter the big slaughterama munitions like nuclear bombs to redirect the nuclear blast into something else say propulsion for a rocket? But then maybe the enemy may cast and redirect that!.
They'd have to pull several Great Wishes for something on that scale unless they're going around to every single bomb to alter them. With multiple Great Wishes a lot of things are possible, but it's not something you'd see without a lot of mages working together due to the restrictions on ceremonial magic.

If they are going around and changing every nuclear bomb on an individual scale, I'd require rolls against Physics and Engineer with appropriate specializations on top of whatever spells they're using to reshape the bombs. A normal failure on these rolls is likely just going to defuse the bomb, possibly leaking radioactive material. Any critical failure has the potential to be catastrophic for the mage(s).

And do remember range penalties if the mages are trying to do this without touching the wepaons.
