I'm loading 30g of Varget at a conservative 2743 FPS. Well I also had 4 misfires. Primer was struck but no ignition.

Not something you see from CCI primers very often
Well... You said this is the first time you have seen this. Then you said you don't see it that often... So which is it?
What bullet are you using? With a 55gr bullet, that is a very light load. With a 107gr, you are a full grain over max; so that may answer it for you.

I think you should pull your bolt apart, if you have pierced them previously, you may have junk interfering with the firing pin protrusion.
