Description
IMR Enduron 4451 is a versatile, match-grade extruded propellant with a mid-range burn speed in the Enduron line. It is suited to classic rifle cartridges including .270 Winchester, .30-06, and .300 Winchester Short Magnum, among others.
As an Enduron-series propellant, IMR 4451 features copper fouling elimination, insensitivity to temperature changes, ideal loading density, and an environmentally friendly formulation. These defining Enduron attributes make it a focused choice for rifle handloaders seeking a match-grade propellant in this burn-speed range.
IMR Enduron 4451 performs comparably to Hodgdon H4350; however, charge weights are materially different. Handloaders should use data specific to IMR Enduron 4451 rather than treating the two propellants as interchangeable.
Made in Canada, IMR Enduron 4451 is available in 1-pound and 8-pound containers.

4451 Powder
Works great in 243 with 100 gr. Sierra Game King

GREAT POWDER
ive got an older browning BAR in 270 win and had the hardest time getting a load together that was accurate with that rifle and the 4451 was the powder that did it

Love this powder
I use this powder for my 6.5 creedmoor shooting 123gr ELD. I tried what the book said but I wasn’t satisfied so I looked at burn rates and figured I’d try IMR4451 and at 70 yards I was shooting a nickel size group. 43.9gr worked great

IMR 4451
Great powder for 280AI. 143 grain Hammer Hunters, 55 and 55.5 IMR4451 produce consistent sub 1/2" 5 shot groups at 100 yards.

Accurate powder
Had difficult time getting a new Christiansen Arms Ridgeline to group. Was using STaBall with mixed results, mostly bad. Tried H4350, better, but not great. Had 2 cans of 4451,started at 46 grains, working up to 47.2 when I hit a very good node. 5 shots inside. .5 inches, best 3 shot group was .343, 5 shots at .567 inch. 139 SST, Lapua brass, federal LR match primers. Very pleased now.

Imr 4451
Simply amazing!! Works well in many calibers! I am shooting almost hole for hole with 25 06 and 280, definitely my new go to powder
-
very pleased
This seems to be a consistent and clean burning powder suitable for my 6.5 Creedmoor. Velocities are not the fastest available but here you dont have much soot and it meters well.

4451,My rifle loves it.
I have played with a lot of powders and IMR 4451 keeps turning up as one of the best. My 6.5 CM just loves 41.3 grains under a 143gr ELD-X bullet. Set at 2.820 Coal. Great deer load and all the holes touch at the range. Tends to shoot best just a little under max.

IMR 4451 30-06 loads
This has become my go to when I can't find any 4895. Shoots super clean with good velocities. I use 54grs with the 168gr HPBT and 55grs with 150gr HPBT. Highly recommend if you usually load 4895 and can't find any.
