IMR 4166 powder? - 10/07/17 02:54 AM
Any have any experience with the new IMR 4166? I've been using IMR4064 for my loads out to 1,000 yards, with great results, but I'm thinking about trying a powder with less temperature sensitivity, to reduce variables. Just trying to decide between the IMR4166 or Varget. My application is a 308 bolt action target rifle.
