On the old scout site I asked if TBAC ever tried reducing the bore of the 338 ultra to 6.5 or .30 . There seemed to be some interest then the site changed and I forgot for a while. Just curious if it was ever built and how it metered.
 
How does the 338 compare to a ultra 9 sound wise on a .308?

Are 16" suppressed 308s a lot louder than 20" or does it just sound that way because the muzzle is closer? Thanks
