Tree Rat Posted July 16, 2004 Share Posted July 16, 2004 Did some testing today in 9mm. Kimber Stainless Target Winchester Brass Star 115 FMJ @ 1.140 WSR and WSP 81 degree's 47% RH 4.0 N310 with WSR Low 1147 High 1172 Average 1162 Spread 25 SD 7.11 PF 133,653 4.0 N310 with WSP Low 1119 High 1150 Average 1131 Spread 31 SD 7.34 PF 130.077 4.3 N320 with WSR Low 1134 High 1179 Average 1158 Spread 45 SD 12.49 PF 133,118 4.3 N320 with WSP Low 1121 High 1178 Average 1145 Spread 57 SD 13.47 PF 131,635 The N310 load average increased by 31, was outside the spread, so it may be valid. The N320 load increased only 13, is well within the spread, and is inconclusive. Primer flow was eliminated but all loads still show minor flattening in the 1911, but none in the H&K USP when firing a few rounds (nother story). Did not do the search. Hopefully some real world data might be more useful and justify the bandwidth. TR Link to comment Share on other sites More sharing options...
RobT Posted July 17, 2004 Share Posted July 17, 2004 Good post Tree Rat! - What sample size did you use? Looks like there should be statistical tests that could be applied to data like this. Where is a statistician when you need one? I may have to dig out my old stat texts yet. Thanks for taking time to put together your results. RobT P.S. How did you measure relative humidity?
