WM's clarification showcased critical info was omitted by OP. Possibly to make sure he had the strongest case on here (11yr old second-hand reloaded ammo?! Cmon). Afaik, we don't know the full story and it would be unprofessional of WM to leak the entire "series" of emails to the public to clear their name on this forum. Worse comes to worse, maybe they need to make a video or a full length post explain the entire situation. But like someone else pointed out, this is all coming from a single source. Maybe if there was an onslaught of other members sharing a similar experience I'd be more willing to side with OP. But too little is known from either side to truly know who's in the right or wrong. (Imo both are prolly in the wrong to varying degrees XD)
In the grand scheme of things, a good rule of thumb is don't shoot reloaded ammo you bought in something expensive/priceless if you don't 389% trust it. And keep your receipts :P
This is good drama though ngl
