Many of these powders worked well with An array of 7mm bullet weights, although a person was restricted to an individual weight bullet.

I then applied the Prometheus Gen II Powder Scale to throw all fees. I've checked the Prometheus several situations with a substantial-stop Sartorius analytical scale, and every time it confirms what I currently know: the Prometheus is precise all the way down to an individual kernel of powder! The Prometheus isn’t low-cost (commences close to $3,800), but if you reload as much as I do, it may possibly help save a huge amount of time, and allows me to Visit the assortment rather than sitting all over loading all day long.

I ran the two rifles with loads to 59c and stopped. No stress signals and received uniform groups in the vicinity of .5" with the load.

I’ve been surprised prior to! I prepare to check my great deal of powders myself and see what I locate. I possibly gained’t have time to do this until nearer to hunting year, so you might take a look at yours and find out what you're thinking that.

Todd Hodnett is one of the fellas I respect by far the most inside the long-selection planet. He’s an authority among specialists.

They sat from the cooler for 4 several hours to guarantee they had been evenly acclimated to the temperature. A thermometer was put inside the cooler with them to measure what the final temperature ended up remaining.

The exam rifles were cleaned with Otis O12-CU copper remover immediately after Every range session. When we are not able to say that all copper fouling was eliminated, we can easily state there was a lot less buildup than typical and what remained was very easily eliminated with a number of wet patches. That may be a authentic in addition for target shooters, who can go through quite a few hundred rounds each day.

Would've been awesome to determine Alliant Reloaders temp sensitive powders analyzed, or else not a nasty report, didn’t expect there for being Substantially of a differnce considering that the businesses are each owned by exactly the same men and women.

Interesting Take a look at. One thing I observed is that even though IMR4166 didn’t experienced the smallest muzzle imr enduron powders velocity for every degree fahrenheit variance, It appears to get essentially the most liniar features.

The aim of the field exam was to quantify the temperature stability of the popular Hodgdon H4350 and Varget powders and Evaluate Individuals to IMR’s new Enduron line of powders. To accomplish this we carefully measured muzzle velocities of meticulously loaded ammo in excess of a big selection of temperatures.

DuPont accustomed to make a huge amount of powder during the US, and operated like 40 some facilities at one particular time, Nonetheless they were broken up right after The federal government shut them down as a IMR 7977 consequence of anti-belief legal guidelines to prevent the monopoly they'd. Hercules took around some in their factories, and IMR (Beforehand owned and began by DuPont) operated stand by itself for your little bit just before expanding into imr 7977 in stock copyright.

Here is a look at with the underlying information, which displays the standard muzzle velocity for every group of ammo:

Wow. Thanks so much for sharing some data on one other powders. That actually helps place these brings about context in the more substantial photograph. And that’s interesting with regards to the N140. I guess that corroborates what I found relevant to the modify in muzzle velocity not getting linear with temperature transform. I agree that you shouldn’t just choose the normal.

You didn’t cover the problem on the rifle all through these checks. Even though the powder might be at a specific temperature as it’s put in the feed ramp, it’s rather challenging to forecast what the temperature from the load will probably be for the duration of the moment of firing – esp. if it’s been sitting down from the chamber for various seconds – brass will perform most current heat quickly.
