[QUOTE="MNbogboy, post: 826626, member: 18849"] Lots of things might come into play here....Sunny days are rough on a lot of chronos...reflections off the bullet can cause premature timer starts or trips.... Another thing you mentioned is only 29 rounds down the tube....Makes me suspect that you may still be using "new" brass.....Usually it takes me 2 or three firings before the brass has stabilized..... The list of course goes on & on....(powder charge variance, primer seating, neck tension etc.) Your SD for the six shots was just a tad over 19....That is about 1/2 the way there already...My guess is the next time you try (on an overcast day) with two or three fired brass that your ES and SD will be a lot better..... Good shooting, Randy [/QUOTE]
