Description
IMR Enduron 8133 is the slowest-burning propellant in the Enduron family. Built for magnum applications, it provides ideal loading density that nicely fills the case at maximum charges, contributing to uniformity and accuracy.
This true magnum propellant delivers outstanding performance in 6.5-300 Weatherby, .264 Win Mag, 28 Nosler, and .300 Rem Ultra Mag, among other cartridges. Its loading density is tailored to the needs of magnum cartridges, making it a focused option for handloaders working in this class.
As part of the Enduron series, IMR 8133 features copper fouling elimination, insensitivity to temperature changes, ideal loading density, and an environmentally friendly formulation. It performs comparably to Hodgdon Retumbo, though charge weights are materially different.
Made in Canada, IMR Enduron 8133 is offered in 1-pound and 8-pound containers.

Enduron IMR 8133
This was suggested by Holbrooks. I purchased a pound, experimented and found the proper grains for 338LM, 300gn Bergers. It makes repetitive holes at extra long distance. The occasional fliers are my fault, squeezing during the heartbeat stroke. Only problem is it is hard to find. When I receive emails, the stores are sold out, again.

8133 loads in a 28 Nosler
I started with a load a full grain less than max. It stuck the case and jammed my ejector into the bolt! Obviously way too hot. I tried another load 3 grains under max, still way too much pressure.

30-378 with IMR8133
Start at their starting load! Their max load is way too much. I loaded some 212 grain eld-x with 107 grains of IMR8133 and it stuck the bolt in my accumark. I can't even imagine what would happen if you put their suggested max load of 109 grains behind a 220 grain bullet. Hodgdon needs to rethink some of these numbers as I have noticed other calibers with max loads that are way too hot. I noticed their Retumbo load is way to hot as well.

6.5 PRC
Finally found a great powder for my 6.5 PRC Browning LR X-bolt. Dialed scope in at 100 yards using 143 ELD-X and 59.0 grains of IMR8133. Results were night and day compared to other powders. 4 shot groups at 100 covered with a dime! 200 yards nickel size groups. Amazing!!!

IMR 8133
Been loading my 7Rem Mag with 8133 for the last two years. Have found it to be very accurate and consistent: sub 0.05 moa with es <20. Very happy with this product.

Ballistics for the above caliber is very impressive using IMR 8133 reloading powder!!
