Thread: Kimber Montana 308 Load Development

Worked up to Hornady's max listed load data with CFE 223 using 180 gr Sierra PH's in a 19" barrel Sako and achieved just under 2,600 fps with mild pressure signs. Then started with their max recommend load (which is not safe practice) with 150 gr MK's and got an average of 2,873 fps with moderate pressure signs i.e. no sticky extraction or overly flattened or cratered primers. Will cut that back at least a grain to reduce throat erosion. Haven't tired 165/8 gr bullets with CFE 223 but will do so next week.

CFE 223 shows promise of being a very good powder for the .308, at least in my rifle and a lot cleaner burning than the W748 and W760.
