Last weekend I was working up some loads for my .220 and IMR 4064 and a 50gr bullet. The first loads I had were six rounds with 37.5 gr. The first four fired measured in th 2400 fps range. I knew that was wrong, so I colored the last two with a felt tip marker and got readings of 3700fps. I couldnt get a sd because I only had two good readings. Thats the way it goes. Load more and test again!
