I don't see why I should expect anything less than well made cartridges for that price, a .22LR is much, much cheaper than the .17 HMR and I have very few problems with badly constructed rounds. Accuracy is another thing, but the cartridges are well made.
It's all about scale. A HMR case is pennies to manufacture on a mass scale, as are the heads, powders and priming compounds. A centrefire is a thicker case to withstand the pressures it creates, there is far more powder and the primer is a separate entity. I don't think some of the prices you see for centrefire rounds is justified but
