Suppressor diameter

[puddleglum]

Hi all,

Is a larger bore suppressor going to be louder than a smaller bore one, assuming other factors are roughly the same?

For instance: three rifles chambered in 6.5-06, 338-06, and 375-06 - same barrel lengths, loaded to roughly the same bore pressures and roughly the same amount of powder burning. The 6.5-06 using a 6.5 can, the 338-06 using a .338 can, and the 375-06 using a .375 - all three suppressors the same size, baffle configuration, etc. - all three moving supersonic.

Would the 375 be louder than the other two?

Would first round pop be more noticeable with the larger bore?

Thanks,
