I only do what the voices in the head of she who must be obeyed tell me to do. When she says if you want it, buy it, then I buy it. Sometimes I do listen to the voices in my head.
The 22-250 is a pretty hot cartridge. The cartridge also has an interesting history from its inception as a wildcat to its development and release in around the mid sixties by Remington. Take a large case and neck it down to push a little 22 caliber bullet. over 4,000 FPS in the case of 40 grain bullets. Plenty of really nice cartridges were born of Savage cartridges like the 22-250 being the spawn of the Savage 250. Since you already load 223 Remington you will have another rifle which can share .224 diameter bullets. The only possible downside to the cartridge is when loaded hot there is some throat erosion but many who shoot and love the cartridge do not see that as a problem, matter of fact, my take is those who love the cartridge really love it and swear by it. I guess if it trips your trigger then go for it. Just be aware the sale of 22-250 rifles is closely monitored by prairie dogs who will place your name on a black list.
