Breech Plug recommendations for RUML

Hello ,



Looking for some help.

I run a pretty much stock Remington Ultimate muzzle loader. Shooting Blackhorn 209 with Parker BE's.



I notice at the range yesterday that the primer in my brass is getting some movement. The primer does not stay in the seated position.



I read on line this morning this is because of head spacing problem that does not get a good seal to the factory breech-plug.



It looks like there a a few upgrade breech plug systems on the market.



Does anybody have a recommendation on a new breech plug system ?



Thanks

Steve
