[QUOTE="J E Custom, post: 996061, member: 2736"] Hello Roy. That is what I do every time. If I neck down I use the (Donut) to head space the round buy short sizing the neck brass .004 to .006 shorter than the chamber. (You can close the bolt on it and it will fire form with zero headspace) this holds the case firmly against the bolt face to center it in the chamber. Then I charge it with a starting load of powder and get a well formed case and excellent accuracy if you want a little more velocity you can bump your favorite (Tested) load up by 2 grains less than your maximum and you can use it like it is. If you neck up to a larger caliber. then I use a starting load "only" and seat the bullet .005 into the lands to maintain zero head space. both methods work and accuracy is excellent. Often I build several rifles for someone(1 a match grade rifle and one a hunting weight rifle with the same chamber head space so the owner can Hunt with his hunting rifle and fire form brass for the match rifle and the hunting rifle. A friend has this set up and has taken deer beyond 600 yards while fire forming his brass. All rifles will normally perform better once the brass is fire formed but with the ability to hunt (Even if it is shorter distances) and fire form at the same time, saves barrels and components (Money). Brass needs to be well fire formed or you will have to fire form it with a stiff load to be ready for accuracy testing. Other methods don't produce sharp angles at the shoulders. :And the cornbread taste like crap. It is not the only way to fire form but it is the way I do it. J E CUSTOM [/QUOTE]
