More results for the .30-06/165 from yesterday's disaster epic
day at the range. All in a NULA M24, 24" #2 barrel. Below are average velocities 10' from the muzzle on a Shooting Chrony, plus group size. All averages and sizes are 4-shot groups. Range temperature was about 55 degrees, but felt colder because it's roofed and there was intermittent wind of up to 15 mph or so.
165 Nosler BT:
55.5/H4350: 2826 fps, 1.43"
56.5/H4350: 2880 fps, 0.91"
57.5/H4350: 2928 fps, 1.32"
165 Hornady Spire Point:
57.0/H4350: 2824 fps, 1.01"
58.0/H4350: 2948 fps, 0.67" (!)
59.0/H4350, 1.09" - no chrono reading due to direct sun on the screens, but it would clearly be hot.
All were in new, neck-sorted Remington brass with Federal 210M primers. Once-fired brass would likely have less runout and give even better accuracy.
As JB has noted before, there were no traditional pressure signs of any kind with any of these loads. It would clearly have been possible to reach grossly excessive pressures without knowing it.
For my own future use, I'm going to use 56.5 grains with the Ballistic Tip and 57.5 with the Hornady. I may experiment with seating depth for the Ballistic Tips since I have a lot of them.
