It depends on what you are after.
If you want a training rifle that you can practice with for less $$$ to improve your shooting technique, which you can then transfer to your center fire rig, and if your criteria doesn't change, the Savage TR could do that for you.
If your criteria does change, meaning your accuracy standards go up for your trainer, I would suggest you get a CZ 455 or better.
I have a Savage TR and I have found that it is not as accurate as I would like it to be and this leaves me wanting an upgrade. It's just a natural tendency for accuracy minded shooters to strive for. That being said, my shooting technique has improved measurably by practicing with my Savage TR, so, mission accomplished.
Since ammo has gone up and become more scarce, I think I may be getting a little rusty with my shooting skills. My ground game (jiu jitsu) has been getting pretty slick though.
The point being, I have more time to look at my Savage and wish it were a bedded CZ PT with a Lilja barrel instead of just practicing and improving with what I got, even though what I got functions as a trainer just fine.
