I don't know if this is the right place to post this?
Anyway after having a lot of trouble setting the head space on my 6.5-284 I have more questions than answers now.
To start with I think I finally got the head space on it set right but there is a lot of difference between book numbers and my gauges and factory ammo? So I then started checking some other rifles, 2, 260's and a AR10 in 308. The go-gauge is a 308 that I use for all 3 rifles and it reads 1.623 and it is almost .007 to short for the 260's and in the AR10 it won't go into battery. All three rifles are set at factory and shoot fine with factory or reloads. So what's right? Book says that both calibers should be 1.634 to the datum line using a .400 comparitor. So is there something I'm missing?
