I've had 204s in the RAR-Predator, Remington 700, and Savage 11.
The RAR-P shoots both the 32 and 40 grain Fiocchi BT ammo sub-moa, but groups start to open if I don't clean it after every 50 rounds.
Here are a couple that I saw on the 'net.
There is a Savage 11 package gun in 204 with a Nikon 3-9x40 on GB for $400, the seller is MIDWEST77.
Whittaker's has a Howa Mini for $330.
