IMR 8133 Powder In Stock
Production of IMR powders dates back over 200 years, when the company was originally founded by E.I DuPont. Available for use in many reloading applications, the IMR series of powder is trusted by reloaders all across the globe.
IMR Enduron 8133 has the slowest burn rate in the Enduron family. Loading density is perfect for magnums, contributing to superb uniformity. This is a true magnum propellant, yielding outstanding performance in 6.5-300 Weatherby, 264 Win Mag, 28 Nosler, and 300 Rem Ultra Mag, among other cartridges. Loading density is perfect for magnums, nicely filling the case at maximum charges, contributing to superb uniformity and accuracy.
The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density, and being environmentally friendly.
IMR 8133 performs comparably to Hodgdon Retumbo but charge weights are materially different.
Important Information:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
