I'm moving to Puerto Rico and there's no way for me to transport ammo, primers or powder. I'm doing my best to sell as much as I can however for whatever I can't sell can a family member in Massachusetts hang onto it for me? They have a FID and license to carry however they don't have any firearms... yet. I wanted to make sure that if for any reason the gov searched their property and found 10k rounds of ammo and 10k+ primers, 20+lbs of powder and a bunch of projectiles that they wouldn't be charged with something.

They will be fine with storing ammo since they have the required gun license. It just needs to be locked up.

may want to look at the local regs on powder storage, some counties (if not all) have limits etc here in VA, but no one goes by them

however it may make a difference if ever inspected or the house catches fire

I am not a lawyer this is not legal advice.

1) Exemption: License, Registration, or Permit: In accordance with the provisions of M.G.L. c. 148 § 13, the Board hereby prescribes the following quantities of explosive materials that shall be exempt from License, Registration, and Permit and may be kept, or stored in a building or other structure: (a) Small Arms Ammunition 1. Not more than 10,000 rounds of rim fire ammunition. 2. Not more than 10,000 rounds of center fire ammunition. 3. Not more than 5,000 rounds of shotgun ammunition. (b) Small Arms Ammunition Primers 1. Not more than 1,000 caps or other small arms primers. (c) Smokeless Propellants 1. Not more than 16 pounds. 2. Persons under 18 years of age may not keep or store Smokeless Propellants. 3. Not more than two pounds of such propellant shall be stored in a multiple family dwelling or a building of public access. (d) Black Powder 1. Not more than two pounds. 2. Persons under 18 years of age may not keep or store black powder. (e) Exempt quantities of small arms ammunition, primers, smokeless propellants and black powder shall be stored in original containers and such containers shall be stored in a locked cabinet, closet or box when not in use. (f) Special industrial explosive devices when in quantities of less than 50 pounds net weight of explosives.

A local fire marshal/chief or city/town can have more restrictive limits but not less restrictive ones.

Any more than listed requires a special permit.

The rules are included here: https://www.mass.gov/files/doc...sued_%202018.1.2.pdf

Smokeless powder is up to 48 lbs. with a permit and 16 lbs. without.

Thanks guys, I really appreciate the replies.
