Gave the marlin 30-30 another try and the ammo I loaded didn't even go bang. On inspection it appears my firing pin is broken as it didn't make a mark on the primers. See the luck I have.

Fortunately I had my Ruger Hawkeye 270 and again stellar results from that rifle and case thus far. No matter if it's factory ammo it's awesome but my reloads flat out are amazing. I can't say that for other cartridges I've tried.

I still need to learn more about the internals and components making up dies and the tooling.
