IMR 4166 is one of IMR’s Enduron relatives of propellants. Enduron powders are formulated to cut back fouling and to be stable throughout a large temperature assortment.
The authors would like to precise their honest due to the citizens with the Melong Subdivision for his or her knowledge and support to perform this investigation.
Copper fouling reduction – these powders contain an additive that significantly minimizes copper fouling inside the gun barrel. Copper fouling ought to be negligible, enabling shooters to spend more time taking pictures and less time cleaning a rifle to keep precision. Temperature transform steadiness – the Enduron line is insensitive to temperature improvements. Irrespective of whether a rifle is sighted in throughout the warmth of summer time, hunted in a November snowstorm or hunting various places with drastic temperature swings, stage of impact with ammunition loaded with Enduron technological know-how might be really reliable.
A couple seasons back, PrecisionRifleBlog.com (PRB) printed an important field check of powder temperature balance. The examination was made to quantify the temperature balance of Hodgdon H4350 and Varget powders when compared with IMR’s Enduron line of powders, exclusively IMR 4166 and 4451. The outcomes ended up incredibly attention-grabbing, to convey the the very least…
Periplaneta americana was the most frequently trapped in Melong Subdivision. This remark is in settlement With all the results of Ejimadu et al. [24] in Jos, Nigeria but is in variance with promises completed by Ebeling [26] that B. germanica reproduces a lot quicker than some other household cockroach rising from egg to reproductive adult.
” with a smirk he responded “It’s a proprietary components”. Being among the simplest men and women from the field to speak to, a mystery this guarded surely sparked my curiosity, so I manufactured sure to get a test sample.
He is not Improper, I had been considering much more alongside the strains of emphasis and wanting to be optimistic, I assume lol.
Deciding on 4166, I decided to utilize it instead of my typical preference of Varget in the known precise cartridge and rifle combination. The parts in query make up my assistance rifle load in .
Getting the rifle back to your workbench for any IMR 4166 cleanup proved the assert—it had just about no copper fouling, as tested with the absence of the blue hue within the exiting patch soaked in Sweets 7.62 bore solvent.
Thanks John, 4064 hasn't been a difficulty here. Varget, effectively superior buy it whenever you see it. I do see a superb provide of 4166 so it seems like effectively worthy of seeking.
Outstanding flow properties assure dependable metering and demand weights for repeatable results with progressive loading gear. It is the choice for shooters who demand precision and accuracy. IMR 4166 Made in Belgium. Specifications: 1 lb. container
Hodgdon Serious Collection powders have attracted quite a fan base, with in excess of 90% of the very best shooters while in the Precision Rifle Sequence picking to run one of those powders. IMR lately unveiled a fresh line of powders “with Enduron Engineering” — which can be also promoted to own “Excessive temperature balance”.
PRB’s test group also discovered other attention-grabbing trends in the data. As an example, variation in velocity isn't going to appear to be linear throughout the entire array of temperatures.
The top shooters inside the PRS and veteran very long-array shooters in other disciplines have learned to value a temperature-steady powder. That’s mainly because a change in temperature can impact the trajectory or “flight path” on the bullet in two perfectly-known methods:
