I wasn't very impressed with it. I like the tcu cartridges better. I believe it was designed to fit and feed an ar 15. Since then the 6.5 grendel has come out and is quite a bit more suited for deer sized game.
Btw, yes it is light recoil. IMO there are better rounds out there for an encore.
As far as longevity, time will tell, it is supposed to be a better solution for an entry rifle( more knock down than a 223).
