Muskeg Man, We could argue over caliber and weight of bullet and on and on, so I will simply say' 7mm/08.. Good bullet = 139gr Partitation, Interlock, SST, Ballistic Tip, Accubond, Ballistic Silver Tip Good powder = Varget, RL15, IMR 4320 all are middle of the road burn rate. If your not going to reload, Hornady 139 gr, Interlock, SST, Accubond shoot well in my Kimber Montana 7mm/08. Also you can take your time, and make a Kimber trigger almost as good, or as good as a Timney. Be sure to slam bolt home hard several times, and bounce on the floor several times. (Safety First) I put my wife's finger nail polish on weight of pull screw. Good hunting and consider the 7mm/08 there is a large variety of bullet weights to choose from.
