Re: Bullet runout?
I have been using the Hornady since it was introduced. I really like the gauge, and yes, the straigtening devise will reduce the runout. I prefer to get my set up right from the start so I don't have to use it. I'm don't really know the effect of this but you have to apply a lot of pressure to bullet. I'm not sure whether I'm straightening the neck or cocking the bullet, but my accuracy always seems better if my set up is lined up with less than .003" of cartridge runout from the start. Before I got the Hornady, I used the RCBS for several years. It's trickier to get a good reading but it will also measure the runout of the unloaded case neck in relation to the case body. The nice thng about this capability is that I can see if the case is OK as opposed to the seating process causing runout. Also, I can check the dye for runout, as well as the rifle chamber by measuring a fired case. I have been able to detect dyes that are not straight. The dyes that are straight will produce accurate loads that are as good as the more expensive bushing competition dyes. If the neck size is right, this is a money saver. In my experience, the biggest culprit to runout seems to be excessive pressure to seat the bullet. I also think that runout could be a major issue with factory ammo. I have tested so called "Premium" ammo that produce run outs as high as .007-009". IMO.
