anybody got any easy way to check headspacing on a model 12 lrpv 6br,or how to set up for headspace on a rcbs full lenght die set?

Hornady has a headspace kit you can buy, headspace for 6mm br is 1.160 to 1.170, I would recommend this kit, many times guys who only neck size have tight bolt issues a headspace gage such as this comes in handy, I will give you a example, my 30BR that is a 6br case necked up to 30 cal so it is same headspace just different neck, so at 1.166 is where my cases fire form to but now and then after 6 to 7 reloades they get out to 1.167 or 1.168 well the bolt gets a little tight there so I bump the shoulder back to 1.166.
