Actually, here in MA, we're not limited to how much we can own, rather how much we can store.
10,000 rds of centerfire
10,000 rds of rimfire
5,000 rds for shotguns
1,000 caps or other small arms primers
not more that 16 pounds of smokeless propellent
not more that 2 pounds of black powder
Accoring to 527 CMR 13.04(1)(e)
However, 527 CMR 13.04(2) allows for much great quantities to private individuals with "permits obtained from the head of the local fire department", though, I'm sure you have to comply with many fire safety regulations.
