[QUOTE="J E Custom, post: 1440661, member: 2736"] You are right about the factory rifles not being up to the task and to achieve this level of precision you will need a custom rifle with the best parts most of the time. But don't despair, The equipment you have will do a good job if you are careful. It just won't load perfectly concentric ammo every time. I was very happy with the same setup for many years but just wanted better accuracy and started trying different ways to understand what it took to improve it. If you accuracy is good and satisfies you, then there is little need for these pieces of equipment, then everything helps. At one time I was happy with 1/2 MOA groups. then I wanted 1/4 MOA, and that took lots of effort. When that became possible, I thought why not go for 1/8th MOA. Things got very hard then. And now I strive for 1/10th MOA (That is the toughest neighborhood there is, and not always possible with a hunting rifle. But it helps the accuracy because you cannot leave any stone UN-turned. There was also the mention of the ejector plunger pushing the case off center in the chamber. And It will if the case is sized to much, And also the reason I try not to size the case body at all unless I start having troubles chambering The ejector has enough force to produce false head space readings if not removed so it could definitely push the cartridge off center If the cartridge doesn't fit the chamber perfectly. If you Full length size, the process/philosophy of seating the bullet to contact the lands is a good way to minimize this misalignment. J E CUSTOM [/QUOTE]
