Okay it is screwed in all the way
OK.. now insert the w209 and close the gun... does it touch the busing as it closes or is there an air space between the top of the primer and the face of the bushing? -Make sure the BP is seated on the bottom.
Another test... wrap some teflon tape on the w209 - make it a little fatter so it will not go into the primer pocket all the way. Now close the gun and see if it contacts the bushing when closed. If it doesn't make it fatter...
Once you get contact... try the impossible - open the gun ever so gently trying not to jar the primer or change its seat at all. Then gently remove the bp with the primer in place amd measure OAL... That should give you an accurate head space number... There is one more step but i will share that one with you when you get this homework done... if you are inclned to try all of this...
