For bullets under 55 gr n140 is a bit slow, though kenny gets good results with it and 55s. When you make it down for a shoot with the club I can give a bit of N140 to try for curiosity's Sake.

Mind you I use 39 gr under a 100 gr a-max in a 6.5 x 55 case that will hold 50 gr of N160, (n140 is really too fast for this cartridge) terrible case fill but still shoots 1/2-3/4" at 100. Could probably tighten that up a bit by playing with COAL but as this is a short to mid range target load (<600 yards) that's good enough for me
