[QUOTE="TRexF16, post: 2374961, member: 108912"] Among the other questions the OP has asked are: 1 - How can I reduce runout? (for which he has received a little help) 2 - Can runout be corrected in loaded cartridges. (which I don't think anyone has addressed) I won't pile on too much with "1" except to note that there is lots you can do to load straighter ammo. Google is your friend on that. Buying precisions match type dies is one but that's expensive. Also, lots of options to adjust your own dies to size and load straighter - easy to look up. For "2", straightening loaded ammo, the answer is it's super easy - just buy a "TruTool" if you can still find one. It's just a piece of heavy aluminum angle with a dozen or so precision holes bored through it. Not sure if the old manufacturer still makes them - could not find them online. But this is easy to make. Hole diameter is critical - don't make it sloppy. I have added two custom holes in mine, one to make it a perfect fit for a cartridge I neck turn, and another for the .270WSM, whose neck walls tend to run 2-3 thou thicker than the .270 Win, for which the precision hole in the TruTool was bored. The key to this device is that nothing touches the bullet itself. Some homemade and even commercial tools just tilt the bullet in the case and that is not what you want - the TruTool actually corrects the problem by aligning the neck with the case body if it's off a few thou. You slip the neck into the hole and adjust the neck to body relationship with very slight hand pressure. I understand the common wisdom that .003 runout is plenty good for hunting purposes but I make every round I load under .001 just because I can! In the attached pics you can see the board I attached to mine so I just clamp it to my bench when I need it and store it otherwise. Hope this helps, Rex [/QUOTE]
