If we're talking about BR size cases, I'm surprised nobody has mentioned a 22arc. Near as I can tell, factory brass is still pretty hard to come by, but 6.5G brass is available at pretty reasonable prices compared to BR brass, and stepping it down to 22 cal would be pretty straight forward. With it sharing the same heritage as the PPC cartridges, I'm not sure what advantage any of the BR variants would have on it. The 22 ARC is definitely not in the same class as a 22CM, 22XC, or 22-250AI, but it should have no problems running a 75gr ELD out to 500 yds in a bolt gun.
That said, if most of your shooting is within 300 yds, I'd opt for a 20 practical. Brass is SUPER easy to make for really cheap and it should be really easy to spot your hits and misses, not to mention its cheap to shoot.
Brass cost and availability are pretty important factors for me, and the 20 Practical and 22 ARC look really good in that category. Having a nice rifle is great, but having to pay well over $1 for each piece of brass makes my sphincter pucker.
