At some point I would consider a new stock or Chassis system (with a chassis you don't have to have DBM as its built right in. After that, if you shoot anything where you need to dial in a bunch of elevation (beyond 600yds) you might want a different, more better scope. But for a lot of stuff that should be good enough. If you want to get anal retentive about things you could bed the rifle and bed the scope rail which is stupid easy. If the accutrigger ain't your cup o tea, you could swap it for an aftermarket unit but I don't think you'd gain too much there. But really if you want to get into the LR game, you should get into reloading if you aren't already. Thats the only way to make sure you are as dialed and as accurate as possible.
