No cons what ever.
The only comment would be that for Looonnnnggg Range the heavier the rifle the better. For just long range to say 1200 yards, if set up properly it should work well.
I use a Rem 700 338 RUM pushing 300 SMKs at 2700+ and the numbers are plenty sufficient for big game out there quite a ways.
Of course, it has a brake, most don't which is why there isn't much written about them. Its hard to write with tears in your eyes.
I shot it prone on a bipod out to 1100 yds and it prints good enough, though a little over powered, for chucks.
