My problem is I have too many calibers.
I have the same "problem", I have counted 11 different calibers but it's mainly due that part of my collections are pre-nato era rifles on wich each country made a caliber different from its neighbors.
Regarding more modern stuff, I was struggling to choose between 5.56 and 5.45 and finally, I decided to standardize on 9mm
So I'm in the market for a MP5
