[QUOTE="Trnelson, post: 1310695, member: 42308"] Here are the results from the latest 225 ELDM testing. I will be including more a bit more detail as I think that I am figuring out a few things in regard to this bullet and this rifle... Atmospherics: 67• wind 040@12kts 30.04" HG 55%RH shooting direction 270• CBTO 2.643" exact bullet weight 224.6g bullet base to ogive 0.884" Brass: 2.497" 233.8g twice fired, annealed, neck sized 0.006" neck tension Winchester large rifle magnum primer 5.3g 76.0g Norma 217 Velocity- 2,773fps SD 4 ES 10 over five (5) ambient bore shots Accuracy- 1.42MOA @ 100 yards. Still not close to what I'm looking for and what this rifle has proven able to deliver. I am not impressed with the consistency of these bullets at all. I'm at a bit of a loss as to how and even if I should proceed with further testing. Out of 200 total bullets lot #2170060 exactly 33 shared the same weight and base to ogive dimension. Within just the 224.6g bullet weight I noted base to ogive discrepancies between 0.881" and 0.888" I chose to use 0.884" and 224.6g as it held largest sample size. At this point in testing I have 18 bullets remaining in that sample size. I have a total of 18 different combinations of samples from 2241g to 225.2g and base to ogive measurements from 0.881" to 0.889". [/QUOTE]
