Firing Pin Energy Testing

Sometime in the distant, dark past there was an article published on energy testing rifle firing pin mechanisms by dropping a small steel rod of known weight down the barrel and measuring how high the firing pin would drive the rod on firing. IIRC the author tested a dozen or so different rifles. It was a crude test, but was useful as a comparator. Anybody know where it was published or better yet have a copy of the article? Thanks a million.

How about this,

Make up a plate with a clamp hole for threaded inserts, which match what ever actions have the firing pins that you wish to test.

Assemble two long pieces of melamine coated particle board in the shape of a V, say six to eight feet long. One end of the V trough is attached to a perpendicular end board.

First plate is attached to the end cap of the V trough, which is set up in a horizontal position.

Action is threaded on, plate is adjusted so firing pin centers on a piece of round Delrin rod say the size of a pencil to start experimentation.

Final size/weight of rod is worked out to give good travel from the heavier whacks, following test/comparisons completed with same rod.

Energy measured in inches of travel.
