Not much choice these day, 170 grain Fed/Rem/Win round nose soft points or Hornady LeverEvolution 165 grain. I'd start with the Hornady ammo, since they are priced a bit less at MidwayUSA than the Fed/Rem/Win ammo. Bought 200 Remington rounds a few years ago in order to feed my Marlin 336SD and 1948 vintage Winchester 94.
