Also what the fuck is match grade ammo?
I can honest to god say I have had a gun since I was 12 and have no idea what gun enthusiasts are talking about. Is it a thing to make yourself sound smart or what the fuck?
Subsonic rounds don’t go supersonic. This means they don’t have the sonic boom/crack, and so are better when suppressed.
Match Grade ammo is built to the “National Match” standard, so it’s more consistent and therefore more accurate.
