I bought a Kimber montana in 270 wsm last year that would not shoot better than 3 inch groups no matter what ammo I used. I know it was not me cause I shot my wifes Sauer202 back to back with my kimber and shot less than 1 inch with her rifle. I tried to contact Kimber but got nothing so I sent myKimber to Hill Country Rifle to be accurized. Should be getting it back in a couple of weaks and I can not wait.
