With its Enduron Technology, which provides superb loading density while remaining insensitive to extreme temperatures, IMR 8133 is the perfect choice for pulling trophies off the mountain and excels regardless of the season or elevation you’re hunting.
IMR Enduron 8133 is 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.
One advantage to reloading is the ability to adjust the load ballistics. This is especially true with today’s powders. In the past, available reloading powders allowed the velocity of factory ammunition to be obtained. In most cases higher than factory velocity came with the risk of higher pressure. Today there are powders readily available that allow the reloader to exceed “standard” velocity levels. This is a benefit to shooters and hunters where bullet drop becomes a factor. If you are interested in higher velocity, look at the factory ballistics for the load of interest in your caliber. Then go to the IMR Reloading Data Center and look up the reload data for that caliber and bullet. In many cases, you will find a powder listed which will allow you to safely improve over the factory ballistics.
