I installed the 209 conversion kit in my 50 cal Remington 700ML. I know the manual say to install the breech plug until the rear is even with the front edge of the ejection port. I have always done this, but now with the 209 nipple installed, the bolt assembly slides over the primer and nipple just a tad. Is this ok? There are plenty of threads left on the breech plug so I can go further. If so, how much room should I leave between the bolt and primer?
