A large number of powders worked properly with An array of 7mm bullet weights, whilst just one was limited to an individual weight bullet.
IMR 7828 SSC is really a magnum rifle powder with the exact same burn up amount as common IMR 7828 and uses precisely the same info. Nevertheless, because of the super brief kernels, metering is just about as good for a spherical powder.
That’s an interesting place, Steve. I haven’t at any time read an individual mention that before. I don’t assert to generally be an authority in metallurgy, so that might surely be the situation. And that i quickly confess that Like every check, this wasn’t perfect. I heard a data analyst say a person time “
The self funding of Cal’s investigation and Trump’s candidacy seem to each be coming for their restrictions. Cal has provided us tremendously from his everyday living’s most precious asset…his time.
In truth, every so often We've got witnessed an inversion of your powder temperature – muzzle velocity marriage for a selected great deal of powder wherever the muzzle velocity in fact lessened as being the powder temperature enhanced.
Very good overview. I wish to see another review While using the exact powder besides use Winchester and FGMM primers subsequent. I might also wish to see how other “Intense powders” do like H4831 my powder of preference.
For his pistol it was about three.five% and for and Vaughn’s 270 Winchester rifle, it absolutely was about yet another 3%. Presumably a adjust in barrel length would affect the amount. The radar trace confirmed the velocity rise and after that start the conventional drop thanks to drag really clearly. My assumption is that this write-up-muzzle acceleration would fool a Magnetospeed into examining a bit minimal, given that the bullet wouldn't be very accomplished accelerating when it crossed the very first imr 7977 in stock sensor. I go through somewhere the military located muzzle blast influence in artillery being finished in the main 11 calibers beyond the muzzle, but don’t remember Finding out the barrel length(s) in calibers or peak-to-muzzle pressure ratios they located it for.
You are doing understand that when you alter the temperature with the bullet by that extreme of the mount the Actual physical sizing on the bullet truly adjustments. It’s no wonder the velocities were being different Should the diameter with the bullet is .003″ diverse at These two temperatures. To even get somewhat precise results of this idea the actual rifle would have to be heated and cooled concurrently as being the bullets.
That may be just what exactly we were being endeavoring to do in this article, and I couldn’t agree extra. I do ponder how These more recent powders would do, but I guess I’m skeptical in Alliant’s quality at this point. But, it’d be interesting to find out the data!
It really is very likely that no additional discussion is required, in which case we propose setting up a completely new thread. If imr 7977 in stock however you really feel your response is needed you could nonetheless do this.
The effects had been exciting, to state the minimum! Both equally enterprise’s claim their powders carry out better than this experiment indicated … and that might be the case in different situations. I did detect both of those Hodgdon and IMR 7977 IMR utilized Winchester primers within their exams. I selected CCI BR-four primers, mainly because they provide globe-class regular deviations with my handloads, and since top rated shooters I belief have always recommended either CCI or Federal.

So it’s difficult to attract substantial conclusions within the experiments without having those. Envision If your all the images With this publish disappeared. Seriously the “meat” of the results are in my graphics, so that could erode much of the advantage of my posting. I tried to uncover the first exploration paper to no avail.
Fantastic work Cal. Could you notify me for those who had 100% powder burn off within the 22″ barrel? Also was the velocity determined by the Lab radar and verified with Magnedo, or normal of both equally.
