The leading functions in the Enduron series are copper fouling eliminator, insensitivity to temperature alterations, perfect loading density and being environmentally friendly.
I don’t Assume I recorded any temperatures higher than about one hundred eighty degrees File. Is that this documented in almost any peer-reviewed place it is possible to issue to? You’re a pointy person, but I often consider to deliver third occasion assistance in my posts (like On this a person I referenced Litz as well as research on Kestrel’s Web page). In which can I browse more details on the barrel’s role With this?
The Device also permits you to good-tune the seating depth, Though I’ve found my best outcomes come from seating the primer many of the strategy to the bottom.
I'd Feel for most conditions the temperature with the ammunition is the same at that of the rifle and scope.
They also are formulated to generally be temperature insensitive, similar to what we’ve seen with Hodgdon’s Excessive series of powders.
It’s amusing to Assume it’s difficult to know very well what the “authentic” muzzle velocity is, but which is Everything you’d have to determine to answer that question … and it’s just not an uncomplicated issue to answer.
Hodgdon is just a middle person. They obtain powder in bulk, in sure specs, from powder suppliers and package deal it with their labels and promote it as a result.
In preparing, Jim loaded sixty rounds in each caliber, picking out powder fees within the Hodgdon/IMR guide that approximated the velocities we use inside our common hunting ammunition.

It’s also quite fickle (poor or inconsistent lights, wind, or insignificant aspects in IMR 7977 setup can skew the results). And it diverse up to 10 fps or more from the opposite two equipment. I changed a sensor as well as batteries inside the Oehler 35p, and likewise was meticulous in double-examining every one of the distances and angle of your sensors before the take a look at. Though the readings just didn’t appear to be as reliable as being the LabRadar or MagnetoSpeed. Now I used to be testing the Oehler in it’s default configuration (regular four foot screen spacing, and didn’t have it in a light box). In the event you unfold the screens to 8 foot or perhaps twelve foot, you’d be able to Enhance the overall imr 7977 in stock performance. Concurrently, that may help it become even a lot less effortless.
No matter whether that was as a result of temperature adjust or Jim's taking pictures, we are not able to say. Regardless of the result in, from the hunter's perspective, accuracy was primarily unchanged.
Also IMR 7977 did you evaluate the precision in the group due to the fact temperature impacts lots of Actual physical Qualities of metal?
Below is a superb paper written by an OU professor on “The Myth in the three Shot Group”. I go through it a several years in the past, and I wager you’ll adore it!
I am able to only assume Normal Dynamics (who will make the actual powder) can no longer preserve rendering it for them. I understand they accustomed to make a great deal of powder for Hodgdon and when they had been awarded a huge defense deal they explained to Hodgdon they'd only manage to preserve earning the Enduron powders accessible to them.
