I loaded Every single case at what I understood will be a mild to medium load, in an effort to prevent tension spikes. None of the loads had been “tuned” for the precise rifle we have been testing with.
I then utilized the Prometheus Gen II Powder Scale to toss all charges. I have checked the Prometheus many occasions on the large-stop Sartorius analytical scale, and each time it confirms what I currently know: the Prometheus is precise down to a single kernel of powder! The Prometheus isn’t affordable (starts all over $3,800), but should you reload approximately I do, it can conserve a lot of time, and will allow me to Visit the assortment instead of sitting down all over loading all day.
Speer Bullets, Federal Quality and CCI. The catalog states: “The powder demand weights detailed within our info tables are maximum. For rifle and pistol masses, the most powder prices must be diminished by 10 p.c to ascertain a bare minimum or starting off powder demand.”
When IMR launched their new line of Enduron Technology powders we understood we experienced to test all three. With all of the powders that you can buy, you can legitimately ask, why make new types?
Teams weren't recorded as I was striving to obtain the photographs off as my timer went off promptly to ensure that a “scorching chamber” or “this, that, and the opposite” did not mess up the outcomes. Thanks, Patrick
5 rounds were being fired to determine the typical velocity for every caliber. All recorded velocities were being used to compute the common muzzle velocity and compact sample dimension regular deviation. The remaining rounds had been fired for precision.
Hodgdon will not personal or work any smokeless powder factories. St. Marks, in FL, is the only a single still in the US and final I understood they failed to make extruded powders. Additionally, it wouldn't be Hodgdon's decision for them to really make it whenever they did.
Our exams ensure that the Enduron powders are as unaffected by temperature as any powder might be. If you are a reloader and you also shoot in a variety of ambient temperatures, you owe it to on your own to try these IMR Enduron powders.
For $three hundred, the MagnetoSpeed is a large worth, and I’ve under no circumstances found it not receive a examining with a shot. I Individually believe that IMR 7977 the LabRadar may very well be much more precise, it’s a whole lot simpler and a lot quicker to set up, and it doesn’t hold off the barrel so it won’t have an effect on your shot. Any time you’re testing things such as I are actually, which might be significant.
It truly is likely that no further discussion is necessary, wherein circumstance we advise setting up a fresh thread. If nonetheless you really feel your reaction is necessary you'll be able to still accomplish that.
That is a superb level, Martin! I hadn’t thought of that, however you’re Totally appropriate. There exists some price into a powder Use a predictable, linear imr enduron powders adjust in muzzle velocity.
To prevent that situation, when employing a temperature delicate powder the intelligent option should be to load down therefore you’ll continue being within the variety of Safe and sound pressures even if the temperature rises. But whenever you do this, it probably gets rid of any muzzle velocity advantage All those powders could possibly have provided in excess of those who are exclusively formulated for being temperature steady.
The solution is IMR 7977 easy, the IMR Enduron powders characteristic a built in copper fouling eliminator, are insensitive to temperature extremes and are made up of little sized grains for straightforward metering and precise loading density.
Actually, Alliant has actually been using an additive that prevents a buildup of copper fouling since 2002 in all its Reloder powders, besides Reloder seventeen. (Being an apart, I appeared higher and lower but couldn't locate the new Reloder 26 powder to include.)
