[QUOTE="jdmecomber, post: 1164837, member: 94549"] 4064 showed some promise we did an OCW test, I wont post all the pics just a couple highlights. One of the problems with this powder was at 37 grains it was going 3000 fps and we really didn't want to have that much speed because of barrel wear and we are loading in the winter, so in summer conditions this load would be well over max pressure we test 35.8-37 grains at it was all over the place so it was showing signs of instability 35.8 .664 MOA 36.1 1.11 MOA 36.4 .432 MOA 36.7 .731 MOA 37 .882 MOA We started getting away from the magnetto at this point when we wanted to try and shoot for groups we figured it had something to do with weird harmonics Not sure why the pictures are crooked [/QUOTE]
