Centerfire ammo in the US has gone up but not dramatically like the 22 rimfire. Any caliber Privi makes is between $16-$22 a box with most around $18 which isn't bad at all. Winchester and Remington prices are up a couple dollars a box. Neither 303 or Swissicon is very popular here and generally no shortage. Just not commonly stocked. I'm fortunate to live near two Cabelas and they have just about any caliber in stock that is currently made. But they even don't have a lot of 22.
