I aint. Its up to you what you do but if you cant grasp it then you cant complain if it goes tits up.
Rough definition on google gawd bless it :
"The duty of disclosure arises because the facts relevant to the estimation of the risk are most likely to be within the knowledge of the insured and the insurer therefore has to rely upon him to disclose matters material to that risk. The duty extends to the insurer as well as to the insured : Carter v. Boehm.1 Jul 2017"
Ammunition (1.4S) is classed as "articles or substances that present no significant hazard". Therefore the presence of ammunition is not a material fact. It does nothing to increase the risk of accident, decrease the safety or function of the vehicle, nor significantly increase the risk of harm to people. A material fact is not merely anything an insurer can invent to circumvent an insurance policy, it has a meaning. The fact has to have a material bearing on the policy, the vehicle, other people or the claim.
It is a fact that a bag of bird feed contains more combustible material than a box of ammunition. Have you always made a point of disclosing every flammable item to travel in your car? Do you disclose whenever you or another passenger is wearing clothes made of synthetic material, which have a significant effect on your risk of burns in the even of a fire? Do you disclose whenever you wish to drive on a muddy road, or in frosty conditions? All these are factors much more significant than the carriage of ammunition or firearms.
