I've got a couple of questions about measuring head space. Currently I'm reloading for a 30-06 and I'm getting 2 consistant measurements while using the hornday head space gauge. (Bushing C .375) Hopefully this is enough information. If not let me know. 1st measurement is 2.0350 2nd measurement is 2.0380 I have been neck sizing (with a Redding neck sizer die) and half of the brass comes out at 2.0350 and the other half at 2.0380. There are a few stragglers ouside these above and below but the majority fall into these two numbers. If I full length size a couple they end up at 2.0410 (RCBS die) All Brass is R&P Other variables 2 seperate lot numbers of brass I have not been keeping track of the number of loads on each piece. Each piece has been reloaded 1-4 times What should I do about this? Do I need to worry about it? How can I get better consistancy with the neck sizing? Do you need any other information? Thanks for the help.
