It’s amazing how much apparent difference there is between my 16” 6.8s and my 18-20” 223 ARs, with regard to muzzle blast. The 6.8 is almost pleasurable compared to the 223s. My 16.5” 357 max with even hot loads was the mildest on blast of any rifle I’ve had.....never even noticed any flash at dark. OTOH, the Savage LWH 20” in 243 was a loud little flamethrower. LOL
