[QUOTE="Trickymissfit, post: 458756, member: 25383"] by chance are you using the Forster aluminum lock rings on your dies? I don't use them anymore as they fit too tight in the slot, and aluminum will flex under pressure. I use steel Lyman lock rings that are about .005" thinner. To use them you find the depth you want with the sizer. The run the die down solid with the ram against something you know is parrallel (you can use shim stock in a pinch). Now with constant pressure on the ram, loosen the lock screw on the ring and retighten it. You have now squared up the lock ring, and are good to go. This allows the die body to be able to float alittle better, and with the jaws setup a little loose (I run mine very loose) you should see slightly better case to die alignment. Lastly: I may have missed, but are these numbers run out in the O.D. of the necks? Or a loaded round? If the rounds are loaded, then pull the seater stem and a bullet to see if the tip is bottoming out inside the stem. If it is; they sell a seater stem that is made for the more streamlined bullets. Or you can simply run a small drill in the middle to gain clearence on the nose of the bullet. You only want contact in the area of the ogive. gary [/QUOTE]
