The chemical manufacturing company my wife works for uses a large (huge really) amount of nitrocellulose. They have been
having intermittent supply issues for several years now. They are in no way defense, or in any other way munitions related. It would be devastating to their business if they couldn't get nitro.

For what its worth, SGAmmo is well known for its fear- mongering to boost its sales and profits, based on "industry insider" information. Take anything coming from them with a grain of salt.
