Springfield 1903

I agree with all said above but just want to expand on it slightly with something that shouldn't have to be said, but none of us are aware of your level of experience so...

NEVER accept the tape method as a substitute for actual headspace gauges. It will get you in the ballpark but no closer. When I use headspace gauges I strip my bolts completely including the extractor collar to remove any artificial interference. What you are actually looking for is the bolt handle fully seating or not depending on which gauge used.

If you don't want to spend the money on a set of gauges for possibly one use please bring the rifle to a gunsmith before shooting it. This should be done with every and any old milsurp you may purchase in the future. Beats the hell out of having a bolt sticking out of the side of your head.
