Is that smoke on the Normal case? I.e. far left?

There are some more aspects to consider.

The primer should be slightly lower than the case head. I.e recessed -003 or .005.

FC brass is heavier and in my opinion that means less case capacity. It might be enough to push over the edge.

Bolt disassembly is pretty easy once you get the glue broke loose on the bolt.

You do need to pop the button on the back into the fired notch. Also need to reset it when done!

I use a long handled hex wrench, towel on the bench and put it at an angle and smack it with a rubber mallet.

You should be able to trip the button and see how the firing pin looks up front.
