Having problems with Federal shotgun primers. They don't fit my 209 conversion nipple. I used Winchester 209 primers for a long time but, had to buy some quick and they were out and only had Federals. The Federals stick out of the nipple 1/16" further than Winchesters and fit loosely. Winchester 209s fit flush and tight. They (Federals) look like they'll fall out when carrying during hunting. Is there a difference in 209 primers?
The muzzle loader is a Thompson Center Arms Firehawk Deluxe with a TCA 209 primer conversion kit installed.
