Made a substantial ammo purchase from Marstar in January of this year. Sat in my reload room for a month before i opened the crate to head to the range. Unfortunately found some significant corrosion which caused me concern. Sent a message to Marstar with details of my purchase and some photos. Customer Service got back to me and has arranged for me to return full crate of ammo....all expenses paid.....with shipment to be fully replaced. So often one reads horror stories here. How nice it is to deal with a business like this. Quality folks....quality business. Would never hesitate to do business with these folks again. WELL DONE MARSTAR!!!!
