[QUOTE="AkleyFan, post: 2994872, member: 114323"] I have go/no go gages and will shim them out with layers of tape to find a slight interference fit upon bolt close (usually a stipped bolt) - you could do this with a piece of brass as well. Then I'll use a Sinclair headspace comparator set and/or the RCBS Precision Mic's to find my approximate chamber length. These devices can be used on a piece of brass at any stage of its lifecycle. There are other methods as well. The "best" method it entirely up to you and what you find suits your needs - safely. When you FL resize your brass, the shoulder of the case will move forward. Check a fired peice of brass against a FL resized peice of brass and you should see the difference. Set your FL resizer to give you the appropriate amount of headspace as others have advised. Have fun and be safe. [/QUOTE]
