    Powder choice for 6.5x55 140 gameking

    Just wondered what powder you guys are using for 140grain in 6.5 x55 I'm using N160 with 140 sst at the moment and getting 2700 fps with the max load good accuracy and no pressure signs, I'm just working on a load for the Sierra 140 soft point but only getting around 2580 fps with n160 is there a better powder to gain more velocity rifle is a sako 85 with 22inch tube thanks in advance

    I have tried reloader 17 with average results with Amax or SST. The loads are not over enthusiastic because the data takes into account the US suspicion aroundsurplus military rifles I think. I use it in 260 as well which after ladder testing has proved best at around 39 grains.

    I'm using 47.2g N160 under 140g GK in my Sako 75 which produces 2750'/sec. No pressure signs in MY rifle.

    IMR 7828SSC has been a real surprise for me. Best accuracy from three 6.5x55's using 140 GK's. ~Muir
