Re: 338 EDGE
I was shooting a 338 EDGE yesterday and got velocity readings on a 10 round string of 2922,2922,2923,2931,2932,2921,2922,2931,2922,2921 now this is really good with a 10 shot ES of 11 fps, but as you can see something caused 3 rounds to be out of the norm. I went to the box measured the SMK's and found the long occasional variations for ogive to base length. Having seperated a group of one length and same weight I got an ES of 5 fps. Now I don't know if that is the ogive to base measurement or if the ogive to base differences are actually the same on all, but the bearing surfaces are different, then sorting them by ogive to base measurements also sorted the same bearing surface measurments. I can tell you that the sorting & measuring does help.
