What is the IMR POWDERS - Enduron® 4166 8lb Smokeless Rifle Powder?

IMR ENDURON® 4166 SMOKELESS RIFLE POWDER


IMR Enduron 4166 is a versatile, match-grade propellant, with the fastest burn rate in the Enduron line. It is an extruded powder with a perfect burn speed for cartridges like 308 Winchester, 7.62mm NATO, 22-250 Remington or 257 Roberts, among other cartridges. The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density and being environmentally friendly.

This propellant performs comparably to Hodgdon Varget but charge weights are materially different.

Smooth flowing..good shooting
Have been using this to reload my 308. My target shooting accuracy has gone up. Although this could be from a number of factors, powder does play a key role.

Great for moderate calibers
With Varget becoming harder to find than Unicorn manure 4166 has become my do it all powder for 308Win. I'm not someone who chases speed. I mostly load 168-178gr bullets. IMR4166 has given me outstanding results.

Great powder from a great company
This was my second order from Brownells. I received great service in a timely professional manner. I reloaded some 308 rounds with IMR 4166 and recently had an opportunity to shoot these. Unbelievably accurate even with a very light powder load. I would absolutely recommend Enduron IMR 4166 smokeless powder.

Varget replacement
I bought this powder since Varget was unavailable. Every bit as consistent and accurate as Varget! I use it in .223 AR,.223 bench rest with a Remington 700 and .308 Remington 700. As long as this is available, I will stick to this over Varget.
