The only thing I did do was remover the ejector from the bolt. You think this might be my issue?
No, but it does remove one potential tell-tale for reading pressure signs.
Were the ejector still present, you can see an impression the ejector makes on the case head as you begin to get into pressures that are too high. Once you get your bolt back from Greg you amy want to put the ejector back in for a while when you start confirming your loads again, if only to provide more information for your observations.
I think you'll find that, with the bushed bolt & slightly smaller firing pin tip your primer piercing problems will go away even at loads beyond 30.5 grains.
I also suggest you try seating your bullets deeper in increments of .010" too as you may find a point at which they shoot better than soft-seated or on the lands. This not only improves your accuracy but also gives you a margin of safety when shooting in higher-than-normal temperatures, or if you need to clear your rifle for some reason (most often shooting in competition when a cease-fire is called!) without ending up with an action full of powder grains.
One last question - why did you FL size your cases before shooting them for the first time?
Generally that's not needed, and in fact can be a bad idea if you don't yet know what your chamber's headspace is. New brass can be too short for some chambers & if resized may inadvertently have the shoulder pushed back even further which leads to case stretch at best or poor ignition or mis-fires at worst because of weak FP impact or the FP pushing the cartridge forward in the chamber without igniting the primer.
With new cases I run necks over an expander mandrel to even out little dings that happen in shipping (just to make sure they're round) then run a VLD chamfering tool into the necks a little just to take the sharp edge off before tumble-cleaning (for peace of mind & to remove the little brass chips from the chamfering tool) before priming & loading.
Other brass prep operations (trimming to consistent length, primer flash hole uniforming and/or inside de-burring, etc.) all happen after the first firing when I know the cases fit my chamber(s) better.
