Thread: Quietest firearm possible?

My experience with fully suppressed rifles tells me the porting of the barrel does make a huge difference.
I own an over barrel suppressed jw 105, over barrel suppressed 10/22 and a mate had a savage Shorty. The Shorty is very similar to the jw, I'd say the jw is a very good copy of the savage. The savage is fully suppressed which included the barrel porting and it is notably quieter than the jw. The 10/22 had a barrel sound the same as the jw but is notably louder due to the action noise even with an after market polymer buffer.
When it comes to ammo, the higher the grains the louder the noise. I shoot Winchester in all, the 36gr are much quieter than the 40gr and 42 gr. I'm not sure of the exact science why but that is the results of comparing side by side.
The savage easily came out the quietest but it also had the slowest projectile.
