That is the price you will pay for good ammo. I don't see the point in shooting cheap, inaccurate ammo in a target rifle.
In the long run you really need to reload. I can load REALLY accurate loads, using match bullets for around $8-$12 for 20 rounds. It will be made just for your rifle, be more accurate and you can probably get 50-100 fps more velocty than factory ammo.
Even with reloading I still shoot a target grade 22 with good ammo a lot more often, and for a lot less.
