The most accurate bullet and load in my Kimber Montana 7-08 is the Barnes 145 gr LRX with 46 gr of Big Game and Winchester Large Rifle Primers loaded to the magazine length (2.82"). Goes 2,742 fps with little deviation. Under 1 moa for all groups (3 shot) fired at 100 and 200 yds, which is excellent in this rifle. No 120 gr bullets with TTSX, TSX or Hornaday V-max have matched the 145 gr LRX groups on the average.
