TBeazlie Posted February 21, 2004 Share Posted February 21, 2004 I've made the move to an open gun in 38 super comp. I have a new 650 with the new style powder measure and am using 4756 powder. The old style powder measures have always been within 0.1 grain plus or minus but this one was way off at time plus or minus 0.5 grains. 4756 is a new powder to me, but i had the same problem with 3n37 which has always metered well. When i changed back to the old style powder measure it seemed to do OK with the 4756. Whats up with that? Quote Link to comment Share on other sites More sharing options...
