[QUOTE="Kmccord, post: 2296372, member: 99039"] LOL, I could feel the frustration reading the 22-250 groups.. I was there earlier this year with my 6.5 Creed and Berger 140 EH, same type of groups, but my ES and SD was nowhere close to what you are seeing, hang in there you will find it. My Creed with the HH has been from .474 to .690 in both the 124 and 110. I am still trying different powders I have to see if anything will tighten up or provide better velocity. If you have other powders definitely give those a try as I am sure you are aware, something else I had always heard from Erik Cortina, the ES and SD is all to do with combustion and to check powder and primer. I used to have ES/SD all over the place until I quit using my old RCBS Chargmaster as the only source for weight verification. When I incorporated my old balance beam scale with the Chargmaster, I noticed the Chargmaster was throwing half grain off either way, when I started using the balance beam and a trickler to bring up to correct charge, that is when my ES/SD came down. I also use expander mandrels to set my neck tension, this provided better groups. [/QUOTE]
