I have the 90 Peak that was mentioned earlier as denting cases when the bolt is pulled back if 5 rounds are in the mag. There's a pic of it on here somewhere in one of the Sako 90 related posts. I just run 4 rounds in the mag but will look into it more after the season.
Aside from that, the only complaint I have is the LOP is a bit long, especially when layered up on cold days.
I've not worked up a load. The first load I shot through it was great so I just went with it. I've done the majority of my hunting with it this year and it's killed 4 deer and a coyote so far. Still have until early Feb to hunt and it will likely be the main rifle used.
There's a lot I really like about it. Love the integrated pic, the mag/bottom metal design, trigger, option to open on safe, smooth action/feeding. I prefer a zero drop/neg comb/vert grip stock after spending time with the Rokstok/CF Versa/Mt Tracker LR, but for a sporter stock the Peak's is really nice. For a sporter style stock, I've been impressed with how little barrel rise there is with it. More than the 3 mentioned above, but it's still pretty good there.
