What's the ideal .22 build for 100+ yards?

Looking for some guidance into building a precision.22.

I have a cz 457 with nice glass and the boyds stock should I just upgrade this? (Lilja barrel, mdt chassis?) Or is there something better for competition?

Don't care about price sky's the limit on this build.

Thanks guys

Edit: my 457 seems to like SK match 100+ although I haven't tried much of the eley.
