Hi all i am looking for a good powder and load data for the 20 gauge in a moss 500 rifeld barrel. i have the the lee 575-470 and a 575 round ball, this is my first try at slugs and round ball. I have done lots of reading, but would like to know what you all are using under the 20 gauge. I will be hunting white tail deer at 100 yards and under with this load. Thank you.
