Jeff, the information I have got for cases such as yours; ones that are not compression formed, are for use with either the Win 209 or CCI 109 primer and 7/8th. ounce of shot, platic obturator wad and card and felt to thickness (lists 7/16" fibre and 1/16" card undershot wad - closed with a roll turnover). Red Dot 19.5 grains or Trap 100 22 grains. These were all proof teated and found suitable for 2" chamber guns. Other straight wall cases trimmed down to 2" can of course be used. Good luck with them.
