All guns, whether it be assault rifles, or .22lr revolvers, will only get as expensive as the buyers are willing to pay. You cant make money if you price your products out of reach of your consumer. The firearms business is a very competitive market, and the mission of staying ahead of the other guy in sales will help to keep prices from getting too crazy. However I do believe gun prices will continue a steady climb for awhile, especially with the recent "panic"
But I personally dont see rimfires surpassing centerfires
