Perhaps there is a "new to reloading" panic, but it won't do them much good as current reloaders have already panicked and bought most (all) the reloading supplies.
I learned long ago to be prepared. I grew up in earthquake country and kept emergency supplies on hand. I also keep reloading supplies on hand. For quite a few years, almost every time I went to a gun shop I'd buy an extra pound of powder or a brick of primers or a brick of 22s. Whenever I visited a big box store that sold reloading supplies I would wander by the Sporting Goods dept and pick up a few components (never hoarding buying, just a little at a time). I lived through the last 3 panics quite well with my stash, never needed to fight anyone for 100 primers. So much easier to stay stocked up and I could probably reload for a few years without buying any powder or primers and I have more 22s than I will probably shoot the rest of my life...
As for keeping a 1,000 or more rounds of "JIC" ammo, it's not paranoia or fear, it's called being prepared. We are living in uncertain times especially concerning private firearm ownership. As we already see, small steps are chipping away at the 2nd Amendment (ammo is getting more and more difficult to purchase in some states). So with the threat of sumami, forest fires (part of my town was evacuated twice in the last 10 years because of approaching forest fires), earthquakes, pandemics, and God forbid, a democrat, anti gun president is elected in my lifetime, I will still be able to shoot my 45 ACPs (1,100 JIC handloads stored), 9mms (approx 900+ rounds stored) 500 each 30-06 Garand, 7.62x39 for the SKS, 38 Special and 44 Magnum for fun and SD...
