Looking for further information on an Alpine Sporter Bolt Action Rifle chambered in 6mm Remington. Barrel is stamped Firearms Co. Made in England. The importers stamp is Firearms International Miami, FL. which I believe later became Interarms. From what I could find they were made in .243, .270, .308, and 30-06, no mention of the 6mm Rem. Any information would be appreciated, thanks.
