LR----
every caliber is going to have some drift. a 155 shell is going to drift a little bit over 1000 yards. Trying to eliminate drift by going bigger, faster and heavier--- is good to a point---- and I guess where that point is- is a matter of
convenience--- that is how much effort do you want to put into harder to find and use calibers. I never bought the 338 Lapua because its such a powder hog and the cases are so expensive. Performance it NOT lacking on it though. I think where that line falls is different for everyone. I think the 6.5 is perfect for a first gun to Strech out distance and learn some new stuff. I can all ways upgrade to a new chambering later using the Solace and pre-chambered barrels.
The solace looks like a very easy system. Not a budget breaker either - as that kind of thing goes. Maybe more than a new savage - but not much more. And a good platform to build on.
over-rated ? depends on who is rating it and what your expectations are for it. A modern version of the 243 maybe. an somewhat better alternative to 308.... yes.
for targets and smaller game - pretty good. not a 300 winmag. but its not supposed to be.
Great for its "weight class.....? " -- yes.....
