I picked one up 3 weeks ago. It does close to 1/2" at 50 yards with wolf match. The stock is a pile of crap though so you may want to get a tacticool asap.
I'm looking to pick up the TRR-SR soon since I cant find the TR-SR without the goofy rail anywhere. I'm thinking the bolt action will have a slight edge over the 10/22, but the shooter and ammo are going to be the biggest factors.
