 Reloading for the VZ-52 rifle in this chambering is a nuisance in the USA.Boxer-primed cases can be easily formed via resizing and trimming 6.5mm Carcano brass, but these are difficult to obtain.Another route is to use Winchester .220" Swift, but in addition to resizing and trimming, this also requires turning the rims down on a lathe and cutting deeper extractor grooves.
