How much are you guys shooting that you need to pick up 5 and 10,000 primers at once?
Personally, I load 223, 30-06, and 45ACP. When I pick up primers, I typically pick up about 2000 of each. 2000 rounds of 223 lasts me at least 6 trips to the range, 45 ACP will usually last me 10-15 trips to the range, and I've never had to buy more LR primers since my first purchase. Granted, I've only been reloading for about 3 years, but in that time I've only had to pick up primers for the 45 and for the 223 3 times. Maybe I'm on the low end of the spectrum as far as shooting goes, but I'd much rather spend my time out in the field stalking a coyote than plinking away at the range.
As far as real or self-induced, I'd say a little bit of both. The next time I go out and pick up primers, I may pick up an extra thousand of each, but I'm certainly not going to buy 10 or 20 thousand "just to make sure".
There are obviously more people reloading now judging by the emptiness of even the die section of Scheels and Sportsmans Warehouse, but I can't imagine that just new reloaders are causing the shortage. Sooner or later the demand will drop off and we'll be back to being able to pick them up whenever we need them. Until then, I'll probably step up the field work and dial down the range time. I can spend 3 hours in the field and take 5 shots and have just as much fun as 1 hour at the range blasting off a few hundred rounds.
