I know that muzzle pressure will vary based on cartridge, barrel length, projectile weight, powder and more. Wondering if someone has some ballpark numbers for:

50 cal, 29" barrel
300WM 26 barrel
308 20 barrel
308 16 barrel
5.56 16 barrel

10,400 and 13,400 for the .308 based on my near max handloads...
