[QUOTE="mark1070, post: 946622, member: 80093"] Thanks WYcoyote. This is exactly the information I was looking for. I agree with you; the tighter the headspace tolerance, the less abuse/stretching of brass will occur. An added benefit is an increase in precision. The only things I do slightly differently is, use tape on the case head in stead of a shim but I then follow up with the no-go gauge. Process -- I set initial headspace with the go gauge to establish a safe baseline then I insert the sized case. Using the re-sized case, I typically find that tolerances are quite close and very little adjustment is needed. At this point, I also check to make sure my factory loads fit in the chamber. If I back tolerance off, I'll recheck with the go gauge as a safety measure but have never taken the adjustment further out than than SAAMI (indicating factory cases are shorter than SAAMI anyway...). Then as mentioned, I follow up with the no-go just gauge as a safety measure (and for liability reasons). Is anyone else using this method? I'm not a gunsmith so don't take this as expert advice. For those who are experts, any issues, safety or otherwise, with this method? Thanks! BTW - Hello all. I'm new to the forum! [/QUOTE]
