PrecisionRifleBlog.com (PRB) not too long ago revealed effects from the subject check PRB done to quantify the temperature security of the favored Hodgdon H4350 and Varget powders and Review those to IMR’s new Enduron line of powders, specifically IMR 4166 and 4451.
With that staying claimed, these new powders are all the things Hodgdon promises them to be. Look at getting unaffected by temperature, we have been surprised. Look into the tabular success underneath for yourselves.
WARNING: This solution can expose you to steer, which is known for the Condition of California to bring about cancer and start defects or other reproductive damage. For more information drop by -
1. Assuming all other environmental conditions continue being precisely the same, an increase in air temperature will bring about a flatter trajectory due to a decreased air density (less complicated with the bullet to cut in the air).
This good, extruded propellant is the 1st inside the series of Enduron Technology powders. The primary options with the Enduron sequence are copper fouling eliminator, insensitivity to temperature adjustments, perfect loading density and getting eco-friendly.

Based on imr 4166 in stock the capture web pages, most cockroaches have been caught inside the toilets, accompanied by All those caught in kitchens As well as in the houses.
At the time they'd a few dozen rounds loaded with Just about every powder, they went and shot them with Each and every powder at twenty five° File, 65° F, and one hundred forty° F. The muzzle velocity of each and every shot was recorded utilizing The two a LabRadar Doppler Radar as well as a MagnetoSpeed Chronograph.
IMR 4166 has become the new Enduron relatives of propellants. It can be formulated to lessen fouling and also to be secure throughout a broad temperature vary.
The best shooters in the PRS and veteran extended-array shooters in other disciplines have discovered to worth a temperature-steady powder. That’s mainly because a modify in temperature can have an impact on the trajectory or “flight route” of your bullet in two well-recognized techniques:
PRB’s examination workforce also observed other appealing tendencies in the info. For example, variation in velocity isn't going to seem like linear through the full array of temperatures.

As soon as they'd a pair dozen rounds loaded with Every powder, imr 4166 in stock they went and shot them with Just about every powder at twenty five° F, 65° File, and 140° F. The muzzle velocity of every shot was recorded working with both a LabRadar Doppler Radar plus a MagnetoSpeed Chronograph.
In my practical experience, both on Internet sites As well as in outlets, IMR4166 has been a lot more obtainable than IMR4064 because it was launched. Only not long ago has much 4064 been showing up once more.
