In my misguided youth I loaded .310 round balls for a 30-30 bolt gun to dispatch squirrels and other invading varmints . Effective range was about 25 yards. Didn't use much powder. I didn't want to attract too much attention. Might have been Red Dot or Unique. I don't remember and at the time I wasn't keeping records.
Once again I have a need for such fodder. Is anyone doing something similar and care to share information?
Thanks
