Forget if I got mine from Grafs or Midway a few years back. Not common but can get it once in a while. Absolute worst case buy some hornandy leverevolution loaded rounds. Dads 1907-8 32 Special 26 octo win 94 loves them 4-5 inches at 200 yards.
Generally the only bullets I have been able to find are Hornady and speer in jacketed. Montana Bullet works makes cast bullets. I also purchased some bear creek 8 MM .323 that are labeled 32/40 moly coated cast I plan to use for CAS long range ocasionally. Really do not like to shoot dads rifle too often as it is irreplaceable.
