IMO, the most over looked really good inexpensive 22 lr rifle on the market is the Remingon M 597. I have experience with five of them so far. All had barrels that delivered better than expected accuracy. Yes, there are some minor modifications that help the barrel achieve its potential accuracy. I slicked up the action bars, adjusted the triggers and free floated the barrels for a starter. Each mod added to the accuracy. I'm not up to speed as to after market products for the M 597, but I am sure some will be worthwhile and some will be so-so.

I have found my personal M 597 develops pretty good accuracy off the bench with most all ammo brands and is exceptional with a modestly priced target ammo. I have been shooting Nevada's Picket Pin Ground Squirrels out to 150 yds while using W W's 333/555 brand. If the cross wind isn't too much, the occasional kill at 175 yds isn't too much to expect. When you are shooting up to 500 rounds per day the pricey target ammo is not justified.
