I Cronographed my loads in my .243 AI for the first time Monday. My accuracy load was 44.5 gr of H4350 and the Sierra 100gr Pro Hunter at .306, 4 shot group. The Velocity averaged 3115................. Is this fast or Slow? I tried H4831SC but never got that accuracy that I did with H4350 Groups usually were at .587 with 4831 and .306 when using 4350 What do you get in your Ackley when using bullets from 95-100gr............? What powder do you use. My barrel lenth is 24"
