Well, I got lucky again. Win 375 ammo and components are very hard to find. The fellow that I bought the 99-375 called me up. He found a box in his dad's estate that had 1 box of unfired 375 Win Big Bore 250gr, 2 boxes unfired Super-x 200gr powerpoint, 1.5 boxes of win 375 reloads made with 31gr IMR 4198 and Hornady 220gr fn, 1 box of hornady 220gr FN bullets, a box of unfired Winchester brass, a set of Lyman dies and a box of gas checks ... all to my door for a very reasonable price. I also found a lb of H4198 at Cabelas in Woodbury, MN when we visited our kids this weekend.
