Very interesting. It seems that 154 gr. bullet expands even less than I thought it would. I keep looking for Accurate 1680 but I'm having a hard time finding it locally. As for primers, I use the CCI 200 exclusively and I've never had any trouble with it. That Speer .311" 150 gr. Hot-Cor looks like a good idea too. Lots of food for thought here.
