[QUOTE="Razor18, post: 1135208, member: 11395"] Well, interesting thing happened. I had a measuring gauge made based on the SAAMI dimensions of a .30-06, which says case size is OK, if the distance from the bottom of the cartridge to the reference diameter of 0.375" on the shoulder is between 2.0487" and 2.0587". Before having this gauge made, I also ordered a Lyman headspace gauge, where the difference between the GO and NOGO size is about 0.006" (measured with caliper). After recieving the measuring gauges I checked the actual size of my reloaded cases, they were all between 2.0487" and 2.0587" alright, but checking them with the Lyman, every one of them seemed to be about 0.006" too long, being all NOGO! But if this would be true, I wouldn't be able to close the bolt on my Tikka, but it closes easily, without any resistance. I really don't get it: can the Lyman factory gauge be wrong?? [/QUOTE]
