MDT Polymer 10 round magazine for .308 / .223

I have an unused spare MDT Polymer magazine suitable for  6.5 creedmore, .308 or .223 etc  new in packaging.  It was for a Tikka .223 but rifle that has since sold.  Part # 104447-FDE so could work with other calibers but you'd need to check.   I'd prefer trade for powder like Varget or IMR 4350 or Barnes TTSX bullets /part cash if need be.
