I really like the Ruger rifles and the .250-3000 round. Accuracy can be a problem with some rifles, but this can usually be solved with enough work and experimenting.
The .250 is a fine deer rifle, but is a lightweight. Most any chambering from .243 on up can work.....if the shooter is good enough, but the .250 just doesn't have a lot of margin in some situations.
If you own other rifles or accept the limitations of a light rifle the .250-3000 is OK, but there are much better choices for an all-around rifle for any and all situations.
