I have no concerns about small primers unless the shortage continues for another few years. My beef lies with large primers. I wish they had coordinated the heights of LP and LR primers. I like to use LP's in certain rifle cartridges with light cast bullet loads and live in fear of pitting the breech faces of my vintage High Walls and Ballards with them. That fear may well be somewhat unfounded but I've heard enough warnings about it to give me pause.
