Armalite Dedicated .22 Uppers $350
The .22LR is in the same fix....does anyone REALLY believe the industry cannot figure out how to improve ignition reliability and cleanliness? Of course they can, but why bother? The consumer "expects" the round to be dirty and unreliable, so why would the maker worry about product improvement?
The gritty feeling after 100 rounds or so is caused by the glass that is mixed with the primer material to act as an anvil. As for being so dirty, not all of the powder in any given .22 cartridge is burned. For a good in-depth article on .22 cartridges, go HERE.TM
