For the most part the calibers are still with us...
The cartridges, on the other hand... not so much.

How does it produce nearly equivalent velocities at significantly lower pressure?
44 AMP said:What is "about the same" or "nearly equivalent"?? specifically??
Is it within 50fps? 100fpr? 200? because that is also a trap.
[How does it produce nearly equivalent velocities at significantly lower pressure?/QUOTE]
I'm not going to look up specifics,but as a general rule,folks often get led astray on pressure numbers due to the different processes of measurement.
I suspect the pressure data typical of the 300 Savage would be Copper Units of Pressure (cup) Its an older technology that was the standard a few decades ago. As newer tech had not yet emerged,folks often incorrectly called the cup figure psi.
Its not unusual to see 308 or 7.62 NATO pressure in psi,measured by piezo technology (or other)
PSI does not equal CUP. I don't know the exact numbers,but just as an inaccurate example, 50 k CUP might equal 60k psi. Pressure would be the same,its a different scale of measurement.
While a 60k psi load might be a safe,SAAMI load, 60k CUP would be much higher actual pressure,and probably dangerous.
That said,,the .308 does operate at higher pressure than the 300 Savage.
