[QUOTE="Trickymissfit, post: 656709, member: 25383"] that part you'll have to take up with Lilja himself. But as I said before, I did a similar test with a different kind of metal and saw similar results (albeit not 2.75 times stiffer [ if I remember right I saw something in the area of twice the deflection]). Remember that Dan was measuring actual movement of the barrel, and had nothing to do with harmonics Now I don't remember what the bore size he had in the barrel (if he even stated it), or even if it had a chamber in it. My test did not use a threaded shoulder to retain the barrel. I used a heavyduty vee block that was anchored down on the table top of a SIP jigbore. The Mallory Metal was actually placed in a mesh bag and then hung on the steel with wire. I then used a surface gauge with a dial indicator to confirm flex. The vee block had two clamps hold the steel in place that were about five inches apart. I know for a fact that the table top was flat, as I scraped it to less than .0002" in six feet. gary [/QUOTE]
