Has anyone tried these powders for the 6ARC for bullets > 103 grains: Hodgdon H322, IMR 4166, AR-Comp, Reloder 15, Varget. What were the results? A friend uses H322 and says it has worked great in his bolt gun. recipes?

I use Varget at  just off max with 105 gr RDFs for my match load  in my 16" Lilja. Velocity is 2450. It may not be the fastest ARC load around, but my velocity and thus dope, zero and accuracy don't change be it 45° during the first stage on a winter morning, or getting above 100° on the last stage in the summer (I use it in a gas gun match with PRS style props and positions out to 700 yards). I only shoot paper for load development and zeroing / confirming zero, so I don't have a lot of groups with it. This was the last time I confirmed my zero:

   

It won't win any internet speed competitions, but it's come real close to winning a match.

Save your H322 - it's way too fast. Benchmark (which is slower) gave me much better results with 70s, and Benchmark was too fast and gave me timing issues with 95s in my 243 LBC pre-ARC data.

I am going to experiment with some Reloader 15. Probably early next year. My thread is in Bolt Actions, Uintah Precision upper from first shot.
