As Kabob says, I've got one in 300 win mag. I like the gun, and it's a shooter, but it is a BIG rifle. 26" barrel is long. overall weight isn't bad, but it's a bit of an unwieldy rifle to hunt with. I'll have to go look, but I believe I got mine down to shooting .65 inch groups with factory Nosler Ammo - E-Tips.
I've been so busy that I haven't really had a chance to get it out and stretch it's legs, but it is a fun gun to shoot, the brake pretty well eliminates recoil, mine kicks less than my .270's do. But, it's LOUD. I target shoot with the brake on, and hunt with it off, if the change impacted the accuracy, I couldnt tell.
That 28 Nosler is a smoker, go for it!
