PrecisionRifleBlog.com (PRB) not too long ago published outcomes from a area check PRB carried out to quantify the temperature security of the favored Hodgdon H4350 and Varget powders and Evaluate People to IMR’s new Enduron line of powders, exclusively IMR 4166 and 4451.
The authors want to specific their sincere thanks to the inhabitants of the Melong Subdivision for his or her knowing and help to perform this study.
Copper fouling reduction – these powders include an additive that drastically minimizes copper fouling within the gun barrel. Copper fouling really should be minimum, making it possible for shooters to invest far more time capturing and less time cleaning a rifle to retain precision. Temperature modify stability – the Enduron line is insensitive to temperature adjustments. Regardless of whether a rifle is sighted in in the heat of summer time, hunted inside a November snowstorm or searching a number of places with drastic temperature swings, position of impact with ammunition loaded with Enduron technology will be really reliable.
A Meopta MeoStar one.seven–10x riflescope was mounted to make sure an optimum sight image. The illuminated reticle created it quite simple to determine within the black focus on, and Actually was The 1st time I've ever experienced employed the element (now it may be difficult to return).
The engineering in IMR’s Enduron line of powders supplies four very important qualities that enrich both of those in-gun and downrange functionality.
Again to old website Shut When there is just about anything as part of your cart, it won't be brought about into the aged web site.
He is not wrong, I used to be wondering far more alongside the lines IMR 4166 of emphasis and seeking to be optimistic, I suppose lol.
At the time they had a few dozen rounds loaded with Every powder, they went and shot them with each powder at 25° File, 65° File, and one hundred forty° F. The muzzle velocity of each shot was recorded employing Both equally a LabRadar Doppler Radar plus a MagnetoSpeed Chronograph.
The Hodgdon powder enterprise is globe renowned for introducing groundbreaking technological know-how for the reloader. Previous breakthroughs have introduced us the acute extruded line that gives consistent performance regardless of ambient temperature, plus more just lately they've imr 4166 in stock got brought us CFE technologies that deters and decreases copper fouling. The natural way the following stage was to combine The 2 for just a new line of powders.
This great, extruded propellant is the primary while in the series of Enduron Technological know-how powders. The primary capabilities of the Enduron series are copper fouling eliminator, insensitivity to temperature improvements, excellent loading density and becoming eco-friendly.
Creation of IMR powders dates back again about 200 many years when the company was at first Started by E.I DuPont. Obtainable for use in many reloading applications, the IMR number of powder is reliable by reloaders all across the globe.
IMR now offers 4 Enduron powders that address a broad range of burn up prices. They can be suitable for lots of cartridges, from modest varmint cartridges each of the way up to your .338 Lapua Magnum.

The highest shooters while in the PRS and veteran extended-assortment shooters in other disciplines have learned to worth a temperature-stable powder. That’s simply because a transform in temperature can influence the trajectory or “flight path” in the bullet in two well-identified methods:
