Man Frontsight, you are all over the Firing Line with these M1A questions! That is good though, we are all glad to help each other out.

I just seat the primer where they lay. It sounds like we have the same set up: M1A, Dillon 550B. Just put em in there and don't sweat that stuff. You have other things to worry about like whether there is powder in the case or not. Just inspect the primer to make sure it is flush or even a tad bit lower than the bottom of the case. The other 550B hangup you need to watch for is to check the plunger that pushes the primer up into the case. Sometimes powder or other junk gets on top of it or in between the plunger and the primer. You will start to notice dents and if it is even a slim little shiver of brass, lines in your primers. I put my handl forward every once in a while with no case or primer on the plunger and wipe it off.
