IMR Enduron 7977 is among the slower burn off charge propellants in the Enduron loved ones. Loading density is perfect for magnums, contributing to exceptional uniformity. That is a true magnum propellant yielding superb overall performance in three hundred Winchester Magnum, 7mm Remington Magnum and 338 Lapua, between other cartridges.
I understand references that work out barrel harmonics/vibrations and references that existing the temperature dependence with the elastic constants of metal but none that explicitly work out the adjust of barrel harmonics/vibrations for a purpose of temperature because of effect on elastic constants. A challenge.
It’s humorous to Feel it’s hard to really know what the “genuine” muzzle velocity is, but that's Everything you’d have to determine to reply that problem … and it’s just not a straightforward issue to reply.
For that close-person, based on his/her desired accuracy in a provided distance or more than a specified array of distances, these variations of precision and precision with temperature might or might not IMR 7977 be applicable.
Cal Zant would be the shooter/creator powering PrecisionRifleBlog.com. Cal is actually a lifetime-lengthy learner, and loves to enable others get into this sport he is so enthusiastic about.
That is definitely what precisely we had been looking to do listed here, and I couldn’t concur far more. I do wonder how All those newer powders would do, but I suppose I’m skeptical in Alliant’s excellent at this point. But, it’d be appealing to view the info!

Sorry for not looking at your submit much more diligently. Your reviews, since the Brits would say, are place on. For my very own info sets I generate a histogram Besides calculating the indicate and SD. Histograms complement error bars. We're all thankful to Cal and his colleagues for time, energy and cash to expend in executing thorough experimentation.
So I loaded some 270WIN with IMR 7977 based upon a conservative H1000 demand and took them out and shot them.
