Is there any difference at all between a match (stamped headstamp) case and just a regular case??
For example Winchester has a regular stamped case and they also have a "match" on other cases. I know they load them differently with different bullets, powder, and primers (sometimes), but what is the difference in the case itself.

I have no idea maybe case life and density of the brass.

If memory serves me. There isn't any difference in Match or non-match brass. The factory stamps those cases "Match" so you can identify them from regular factory loadings...

That's what i thought. When I weighed two Win cases, 1 marked match and 1 without the stamp, there was hardly any difference. I had thought the match ammo would have a thicker neck at least but both were very close to the same.

Military match brass usually does not have the primer crimped in, which is nice for reloading. There are exceptions, such as a batch of TZZ .45 acp Match brass I have, with crimped in primers.

Depends upon the manufacturer. In the case of Lake City M118 Match and M118LR, as previously mentioned, there is no primer crimp. Also, brass dimensions are held to tighter tolerances.

According to the 1960 booklet given to competitors at the Board matches at Camp Perry, the Frankford Arsenal .30-06 brass of that era also had an extra head-forming "bump" process to insure a tad more uniformity and a bit of extra work-hardening, so the cases would last longer in the reloading cycle for the marksmanship units.
