[QUOTE="Bang4theBuck, post: 2766877, member: 73596"] Honestly, reloading for accuracy better than 1 moa is a process that involves all aspects of process control. Not to say that it is difficult to control the important things, but you need to know what they are. Controlling velocity may not seem important to you now, (unless you meant achieving extremely.high velocities wasn't important) but if you are a handloader, you will definately care about reducing ES/SD. I think sticking with known combinations of powder/primers in certain cartridges is an easy way to reduce variables, and testing time. Example would be 308 win. Varget with BR2 or CCI 200s and bullets in the 155 to 178 range is a no brainer. H4350 same primers with 130-143 class bullets in a 6.5 CM is a no brainer. From there, I would concentrate on neck tension. Depending on your purpose .0015" to .004" of neck tension are usually optimal. If your does are basic full length sizing dies, you are controlling neck tension indirectly, by sizing the exterior of the case, with an unknown neck wall thickness, so you are achieving an ID on the neck that may or may not be optimal for your application. There is lots of variance in neck wall thickness. This is one of the biggest contributors to accuracy in my mind. Varying Seating depth can definately improve accuracy, but is also usually the last tweak, and will often (not always) get you that last 25-30%. Another thing I do with my shooting buddies is let them shoot one of my known accuracy rigs with my tuned ammo to see what the shooter is capable of. If the gun and load is 1/4 moa, and the shooter is only experienced enough to produce 1moa....then it is best to put the work in there before wasting components on accuracy tuning. Build a generic load and practice for a bit. I love helping new reloaders get going and have a pretty proven amd economic system, if youbwoukd like any one on one guidance. Reach out via PM. [/QUOTE]
