I contacted Winchester via their website.
They sent me an e-mail asking me to call one of their representatives.
"Thank you for contacting Winchester Ammunition. Please call me on the 800-356-2666, ext. XXXX and I will be more than happy to help you out on this. Thank you and have a great day."
She sent UPS with a self-paid envelope.
Still waiting to hear back from them.
Don't send it US Postal Service.
