as many guns as you like we also dont have a limit on how many rounds you can own , this is set by yourself .
you put on the form what you want to own (you can update this at anytime as you purchase more )
you also then say how many rounds you wish to have at anyone time , so if you go shooting every weekend you can ask to be allowed to store thousands upon thousands of round as there is no actual legal limit , but if you say you only intend to go shooting once every six months the likely hood is they will say you dont need thousands of round and a limit of about 1,000 would do
