[QUOTE="MNbogboy, post: 1820777, member: 18849"] Another test you might make would be to layer 1 to 4 layers of scotch tape on the head of a fired case. Trim them tight to the rim with scissors. With one or two layers the bolt will probably close but with some resistance. With 3, 4 or more layers the bolt should not close easily or at all. This may tell you with some confidence that the brass in question may have indeed been fired in that chamber. It may also tell you that a loose fit (3 or more layers close easily) that it may be wise to "jam" the bullets as GLTaylor mentioned above to control the headspace as you fireform them to your chamber. The purpose of this "tape" test is in absence of other measuring equipment to help verify a safe condition before firing. Household "Scotch" brand tape is approximately .002" thick. [/QUOTE]
