I have used the Horandy SST bullet in 180 grain capacity and have had success not only in .300 Win Mag but also 30-06 & .308 caliber.
I've found that because of it's aerodynamic boat tail shape as well as a BC of .480 it holds together well with proper expansion and not over penetration , additionally it shoots true.
Yes, it is not the most expensive bullet out there but to me it has proven itself, and that's all that matters!
I have taken Moose, Elk and Whitetail deer with this bullet of course using different chambered firearms all in the 30 caliber range and it has always been a performer for me.
I have considered moving up to the 200 grain Hornady ELDX that has a BC of .626 but have as yet not found the need to perform load development on this bullet ( Please note that I have stated not yet, but perhaps in the future)
In fairness I've also used the Barnes180 grain TSX with favorable results.
You will get as many different opinion's on this matter as there are flavors of ice-cream.
In the end "To Each His Own"
