My 300 BO has a YH suppressor and it is almost as quiet as my suppressed 22 LR.Rimfire is its own animal.
Have you ever shot your 45And your 300BLK can side by side? I'm betting , if you measured them on a decibel meter , they would be pretty much the same volume. My 300 black and my Glock 9mm are about the same volume. It's one of the reasons I only suppressed one or two of my center fire pistols.
"Quiet" is very subjective. We expect a rifle to be loud. And so the rifle can seems really quiet. We expect every pistol can to shoot like 22 rimfire and so when it doesn't , we think it's pretty loud. It's kind of like the people who think nine millimeter is really snappy in a PCC. Highly subjective.
Everybody has their own personal experience and\nSubjective evaluation of how loud "quiet" is. So I can't really make any universal statements about that. I'm just trying to suggest to the OP not to be disappointed. There may well be nothing wrong at all with his setup
It's not the suppressors fault. I have the same one and can get various calibers absolutely silly quiet but on a semi you are hearing a lot of decibels at the chamber. I noticed my 9mm pcc getting quieter just by adding buffer weight to hold chambered closed for fraction of a second longer. I shot a TON of subs suppressed and not every sub load is quiet. You need to achieve the lowest muzzle pressure and not have powder burning outside of the barrel/ can. Smaller amounts of faster burning pistol/ shotgun powders are usually the quietest. I can make a loud 45 caliber and a amazingly quiet but both are 1050 fps..
Yes, you're correct BUT You can have a "loud" subsonic load and a quiet one and both can be 1050/1065 fps. Powder burn makes a HUGE difference with the noise you hear. Less muzzle pressure is the answer to being quiet through a suppressor.
