Jon,
Your likely problem with the primers doing funky stuff in the subs is due to low pressure. Normally the primers will push out of the pocket to take up any room left by headspace. When pressure reaches its peak the case is forced back to the bolt face and reseats the primer. If the pressure is on the low end the case may not come back far enough to seat the primer again. Sometimes they reseat but the primers look odd like they have been flattened to one side and they look like hot load primer flow. I have some loads I know are light and yet the primers say they are hot by the look. Sounds like you are at the same place here....failure to clear the ejection port sounds light load like..... The only fix if you feel its a problem is to change powder. Not sure whether to say go slower or faster but you need to get the pressure peak to move to a different point in the cycling.

Just my opinion of course.

Frank
