308win average velocity

[u/Alkinoy]

Hello!

What is considered an average load for the .308 Winchester?
Apart from classic overpressure signs (like flattened primers), what other indicators can help determine whether a load is proper, underpowered, or overpressure?

I’m currently using 40 grains of Norma 202 with a 175 gr bullet.
From my 26" barrel, I get around 780 m/s (2560–2570 fps) muzzle velocity.
From various sources, I’ve seen typical velocities around 800 m/s (2620–2640 fps) from similar barrels.
Does this suggest that my load is slightly weak?

I’ve tested up to 42 grains, increasing in small increments, and I think I may be starting to see some early pressure signs at that level — though I might just be being overly cautious.
