Immediately after firing twenty five cartridges loaded with IMR-4955, I mopped out the bore with citrus cleaner to eliminate powder fouling and yet again took photos at the identical 3 intervals.

I know references that determine barrel harmonics/vibrations and references that existing the temperature dependence of the elastic constants of metal but none that explicitly compute the adjust of barrel harmonics/vibrations as imr 7977 in stock a function of temperature as a consequence of effect on elastic constants. A job.

This can be my initially write-up listed here on This great site. I'm an avid Hunter, shooter, and reloader. I've been reloading since about thirteen years old and am not forty seven. Really don't claim to know it all but I feel pretty snug with loading ammo.
