I do know references that estimate barrel harmonics/vibrations and references that present the temperature dependence from the elastic constants of metal but none that explicitly determine the adjust of barrel harmonics/vibrations like a purpose of temperature thanks to effect on elastic constants. A challenge.
I thought it had been a wonderful posting. They went to some great duration (like leasing a freezer truck) to test to get it ideal.

Take into consideration all the dope cards you’ve observed printed out.

The IMR 7977 answer is easy, the IMR Enduron powders element a built-in copper fouling eliminator, are insensitive to temperature extremes and so are made up of little sized grains for simple metering and specific loading density.
Good get the job done Cal. Could you inform me should you experienced a hundred% powder melt away while in the 22″ barrel? Also was the speed based on the Lab radar and confirmed with Magnedo, or regular of both equally.
