Yesterday I was depriming 900+ pcs of 357 Mag once fired brass I had bought and I found 62 nickel pieces that had the rims shaved down to .410" and they had a slight taper to them instead of a straight wall. Then I came across a lone brass case that was the same and stamped 351 Win SL.
I had never heard of this caliber before and had to do a google search to find some info. From what I have read, the rifle was produced between 1902 and 1957ish. The ammo is very rare but 357 Mag or Max cases can be sized to fit and the rim had to be shaved down to .410".
Anyone else heard of this particular gun and anyone want the 62 pcs of nickel converted brass? I am keeping the one lone case stamped 351 for my budding collection.
