No, shooting more 209s only adds to the buildup in the breechplug. After a thorough cleaning, I always pop off a couple before I load the first time to remove any ramaining oil or moisture in the breech plug and barrel. I don't think using a primer between shots will do anything but add to the buildup.
Glad you are getting some accuracy. Good luck. Post picutres!
