Own a business as ammo discounter. Commercial parties here have a monopoly. If I would have the money and time I'd go to a European ammo manufacturer and buy a very small selection of calibers in bulk. 115/124gr 9mm FMJ, 5,56 in 55/62gr FMJ and SP, 7,62 in 147gr FMJ, 22lr Standard and HV.. Just that and Standard relaas components like powder and bullets. Drop the prices in a discounter sort of way (buy more = pay less) and only open 2 days a week so that I have a shitload of free time.
Why is that? I pay 11cts for prime quality new made military match ammo (RUAG Swiss P cost price) for which people are bitching on matches. A lot of people stop shooting as the prices went through the roof. Here the cheapest surplus is 45cts for regular ball (!).
I would take great pride in rescueing peoples hobby and I already calculator that it would still be highly lucrative, especially if you keep the selection small. Plus fucking with that (rude) monopoly holder would just be fun.. because they are absolute fucktards. The market is relatively small in Europe, they use that as an excuses to be rude, oncooperative and safe (I.e don't execute recalls as only distributor etc).
After I fucked their business up I'd go into sustainable, Niche market meats by putting some prime cattle (Wiesent, heckrind and belgian white/blue) on a lot of acres. The same with some prime pork (mangalitza x Iberico and mangalitza x duroc). Sell prime meat through Europe.
