The main features of the Enduron series are copper fouling eliminator, insensitivity to temperature changes, ideal loading density and being environmentally friendly. IMR 4166 is the perfect burn speed for cartridges like the 308 Win/7.62mm NATO, 22-250 Remington, 257 Roberts and dozens more. Positively, a versatile, match grade propellant.

Very accurate

By Mark C. on Dec 23, 2016
First of all I tried to get several of my rifles to fall in love with VARGET just never happened.not to say it's not accurate for others ,just not me. Bought 4166 and was absolutely amazed at the accuracy in three rifles thus far. In my LR 308 16 inch 1-10 using 175 gr SMK I get.7-.8 MOA 5 my 8x57 Mauser 1-10 twist using 175 gr sierra pro hunter I get sub MOA from low to high charges.of course shines at certain nodes to get .7-.8 MOA .my other 308 rifle 22 inch 1-14 twist using 168 gr SMK i get .6-.7 MOA . All these are consistent groups and not random and 5 shot groups.also must add all factory barrels!! This powder hoping to get as good as results from my other rifles I own,after all the calibers are listed on the front of the container.

It has replaced my Varget

I finally loaded 50 rds of .308 Win last night to try it out. I was more than pleased with this powder. It is very clean and shot very good groups. I used XX gr on a 150 gr Hornady fmjbt. Like I said I will be using this now in place of Varget.
