For pure 100yd rimfire accuracy,I'd do a 17Hummer bolt gun.
For [bleep] and giggles,I'd twist up a 10/22. The aftermarket stocks and barrels are loot well spent IMHO and you'll certainly realize a performance increase.
Bang for the buck,it's hard to top a BC barrel and a Hogue stock. 1" 100yd groups in fair conditions,wouldn't be inordinate,with selected ammo tailored to the system.
Love them 10/22's!......................
