Yet to see a magnum load that didn't produce a really sharp, obnoxious muzzle blast. So if one is worse than another I could care less cause for anything short of SD/HD I'm using hearing protection.
I was talking comparatively. I'm not trying to say that full power 2400 loads are whisper quiet--I'm saying that my H110/296 loads are really sharp and obnoxious compared to my 2400 loads.
Yes, I use hearing protection too, and yes, the H110/296 loads were still objectionably "blasty".
