Wound’t magnetospeed readings be usually somewhat highter, because it measures the relative speed between exiting bullet and recoiling rifle, and not the relative velocity among bullet and “earth”?
IMR 7828 SSC is usually a magnum rifle powder with exactly the same burn off amount as normal IMR 7828 and takes advantage of a similar info. Nevertheless, a result of the Tremendous quick kernels, metering is pretty much nearly as good to be a spherical powder.
But that’s receiving near the limit of the system’s examining skill, so it could be slight sensitivity variations earning just one device noisier at that array than one other. May be a random little bit mistake artifact. I don’t have a means to know.
That was enlightening for me at the least. I guess this may vary from the lots of primers you have … sadly. So I’m not sure how universal my effects are.
Groups were not recorded as I had been hoping to get the shots off as my timer went off quickly making sure that a “warm chamber” or “this, that, and another” did not mess up the effects. Many thanks, Patrick
I do know copper bullets are more time but dang I would have necessary a fall tube to make it function to have to even close to max load. Shots showed significant strain early on within a rifle that usually likes the edge of max.
Hi. I obtain all of your posts extremely usuful and related. Are you able to give us a much better indication of how the Magneto Speed chronograph measured up on the doppler radar?
Would've been great to discover Alliant Reloaders temp sensitive powders examined, in any other case not a bad posting, didn’t assume there for being A lot of a differnce because the businesses are equally owned by the identical persons.
It actually tracks the bullet out to about 80 yards, taking various velocity readings along the way in which. The muzzle velocities collected proved to generally be very identical between The 2 products, which gave me many assurance in the information. Both equally of those imr 7977 in stock products seem to be a great deal more exact and trusted than classic light-weight-based mostly chronographs. But to test to mitigate any likely measurement errors, we averaged the velocities gathered for each shot from both equally equipment.
In fact, following that exam … I said I wouldn’t ever get it out and established it up all over again. First, it’s a ache to set up compared to the Some others. It’s also pretty fickle (weak or inconsistent lighting, wind, or minimal details in setup can skew the effects). And it different as many as 10 fps or even more from another two products. I changed a sensor as well as the batteries within the Oehler 35p, in addition to was meticulous in double-examining all the distances and angle with the sensors before the imr enduron powders test. Even so the readings just didn’t appear to be as dependable given that the LabRadar or MagnetoSpeed. Now I was tests the Oehler in it’s default configuration (conventional 4 foot display spacing, and didn’t have it in a light-weight box). If you spread the screens to 8 foot or perhaps twelve foot, you’d be able to Increase IMR 7977 the functionality. Simultaneously, that may enable it to be even less convenient.
1 fps or 0.01 fps? Would it alter the team precision at one hundred yards in any way? Wouldn't it alter the SD in the muzzle velocity in any respect? Go to the variety having a given rifle, ammunition, sighting method and platform and determine the team precision at a hundred yards, necessarily mean muzzle velocity and muzzle velocity SD for your presented ambient temperature. Then all person effects which include influence of temperature on powder and any result due to thermal expansion or modify in physical Attributes are “involved” with your measurements. This is actually the classic engineering solution but diploma pf applicability of final results to other rifle-ammo-sight-System programs is probably minimal regarded at most effective.
These properties presents this powder rewards when it will come selecting for elite execution and precision. self-loader loaders which incorporate the 9mm Luger, .357 SIG and 10mm Auto make the most of this powder in gentle of its thrilling Homes.
So it’s hard to attract sizeable conclusions with the experiments without having those. Think about When the all the photographs On this put up disappeared. Truly the “meat” of the results are in my graphics, so that would erode Significantly of the advantage of my report. I tried to come across the initial investigate paper to no avail.
