[QUOTE="Dean2, post: 1672358, member: 26077"] ES and SD are primarily affected by neck tension, variation in case capacity, case fill, powder and on rare occasions primer, pretty much in that order of importance. Work on one variable at a time. Take your fire formed brass, uniform the flash holes, weight sort it and check the neck thickness, or get some Lapua brass to work with. If that doesn't cure the ES look for a powder that gives you as close to 100% case fill as possible and is the slowest powder that produces top velocities (in this case 4350 and the H version is an Extreme series powder and is at least as temp stable as RL16). If that doesn't get you the ES you want try CCI BR primers. [/QUOTE]
