[QUOTE="Ghost7, post: 1205239, member: 89834"] Am I thinking right? Load development for .243 on 105 hybrids and 107 SMKs. Would it be fair to say that a five shot group, with all things considered, that has an ES =16fps and a vertical spread of .250" but overall group size of .600" is now a prime candidate for playing with the seating depth? Is horizontal spread related to seating depth more so than charge? Is vertical spread more so related to charge than seating depth? I've been playing with imr and H 4350 for these loads. Hawk Hill 8 twist on Savage action, Lapua brass, cci primers and whidden dies. .002" neck tension. Not getting the ES numbers I would like but think I'm getting close. Some of the worst groups I have had have had the lowest ES numbers...what gives? Educate me please. [/QUOTE]
