Examining .308 Accuracy nodes

[Front Royalty]

It's very easy to hit accuracy nodes with close to minimum charge weights but your velocity is going to be way down. Using the same bullet/powder combination, I'm getting 2,620 fps with 44.0 grains of 4064. You can go all the way up to 46.0C, which I wouldn't recommend, but just to give you an idea of what charge range you're dealing with...

I use 42.0 grains as my go-to sighting/fouler round, but trajectory validation with any wind beyond 400 yards is a nightmare. Velocity was just over 2,500 fps, and while it's good for 1-200 yard accuracy, anything beyond that range it is pretty tough going.

I'm getting an average of 2560 FPS with 41.4 gr in LC Cases out of a 20" barrel using CCI 200 primers. 42.6 gr is pushing capacity in this thick brass.

ETA: Didn't get the chrono opportunity for the 42.3 loads, but definitely will next time.
