Unless you purchase Ranger ammo directly from an authorized Winchester distributor then you can't be sure of it's pedigree and quality.
Winchester doesn't allow its distributors to sell Ranger ammunition to the general public. If you purchase Ranger ammo from an unauthorized ("questionable") source then you're taking a risk in regard to quality.
List of authorized Winchester distributors, please.
Your input on the places I listed, RE: Their status as authorized Winchester distributors, please.
Your response to overruns being offered to the public and dealers who simply choose to skirt around Winchester's policy, please.
