Here are some real world numbers. In Sept. 2009 I bought 3000 rounds of CCI MiniMag for $6.49/100 from an online retailer (I still have the invoice); that was the best price I could get at the time. The same ammo at my LGS is now $8.99/100; that's without any comparison shopping and is about a 40% increase over almost 7 years, not a 400% increase. I don't think any .22 LR ammo was 2 cents per round less than 10 years ago; that sounds like a 1980's price.

Another long-range comparison that I've mentioned before on this forum is that in 1964, when I was a senior in college, I did a lot of .22 LR shooting. I paid $5.00 per brick of Federal Monark (their bargain brand then) or a penny per round. Applying an inflation calculator, that's 7.7 cents per round in 2016 dollars. That's slightly more than the price I've been paying recently at my LGS for Federal Auto-Match ($23.99/325). The same is true for reloading components and centerfire ammo; they're cheaper now than they were over 50 years ago when adjusted for inflation. These may be the "good old days" and we just don't know it!
