Has anyone tried IMR4064 in a 6.5 Grendel? I don’t see load date in any of my books for it. Looking at the burn rate chart it does fall within the range of powders that are listed. H335 at #86 Benchmark #85 (fastest), imr 4064 #101, Varget at #108, cfe223 at #111 (slowest). Seems to be in the wheelhouse of this cartridge.
How temp stable is IMR4064? This time of year, it is difficult to work a load ladder in Minnesota. -10F yesterday, +30F tomorrow, July will be +100f.
