I bought a Kimber 84L MA last summer and my groups with the 160NP over the max. load of Magpro given by phone by the Western Powders ballistician are slightly larger than that. I think it is my shooting due to the weight of the rig and medical-spinal issues, but, it is showing about MOA and practice will help.

Mine is now rigged with silver Talley QD screwlocks holding a new Leupy VX3 silver 3.5x10.40, VERY nicely balanced and so nice for an old geezer to pack.

Kimber impresses me and I hope they continue and offer new models and chamberings.
