Re: What am i doing wrong guys?
The following is one opinion, from one person. Take it as you will.
Have you loaded any and measured them?
I don't bother measuring runout in anything but loaded cartridges for my guns, unless I know there is a problem that I am trying to isolate.
Knowing how and where to measure runout, and how to set up the gauge, can remove some of the observed runout....at least in the areas we care about. Of course, I am talking about unturned brass in non tight-necked chambers. In this case, the neck will not even make contact with the chamber, so don't even use the outside of the neck for support or measurement.....it really doesn't matter.
The thing we want to accomplish is getting the bullet started into the rifling dead center and straight.
That should be the only goal here.
When we chamber such a round, the only surfaces that make contact with the barrel/chamber are the case-walls, the shoulder, and possibly the bullet. For this reason, I set my runout gauge to to cradle the case at a point just above the web, and another point just below the shoulder(trying to set up on the shoulder would be a bitch). With a bullet in place, let the bullet act as the forward stop and check bullet runout somewhere other than right at the tip. If you feel the need to measure the neck of an unloaded case, set up the tool the same way, let the case-head act as the stop, and measure runout at the "inside" of the neck.....the only place that really matters unless you have a tight-necked chamber.
