This new ammo from Lapua is going to be the most expensive .22 LR ammo when it is released, and apparently the most accurate.

Lapua rolled out a whole new line-up of rimfire competition ammo in three grades, X-ACT, Midus Plus, and Center-X. The ultra-premium X-ACT ammunition, which may be the most expensive rimfire ammo ever produced, is designed to out-shoot the best Eley has to offer.

UPDATE

According to Mooseyard @ RFC

The rep from Lapua at the SHOT show expected pricing to be 20-25% higher than anything else out there. He also said that the people testing the ammo (real compitition shooters) have been seeing group reduction of 30-50%. That’s impressive if true.
