Powder Valley has new IMR 4166 Powder in Stock

Powder Valley Inc. (PVI) now has the new IMR 4166 powder. This is an all-new extruded powder with a burn rate similar to Hodgdon Varget. It is expected to perform well in the .308 Winchester and in 6mm cartridges running the heavier (95-107gr) projectiles. IMR’s press release states: “IMR 4166 [has] a perfect burn speed for cartridges like the 308 Win/7.62mm NATO, 22-250 Remington, 257 Roberts and dozens more.”

IMR 4166 is one of the new Enduron family of propellants. It is formulated to reduce fouling and to be stable across a wide temperature range. If you commonly use Varget, Alliant Reloder 15, Norma 203B, IMR 8208 XBR, or Vihtavuori N140, you might want to try IMR 4166. It is available right now at Powder Valley in both one-pound ($25.45) and 8-pound ($182.75) containers:

IMR4166-01: IMR 4166 – 1 LB. — $25.45
IMR4166-08: IMR 4166 – 8 LBS. — $182.75
