Ok, but aguila sss 60gr. subsonic is not representative of all subsonic ammo.
A fairly large portion of these: http://www.midwayusa.com/find?sortby...ensionid=16330
happen to be subsonic. Subsonic simply means, it's not breaking the sound barrier, which is roughly 1100fps at sea level, a lot of those are 1000-1050 out of a rifle(and sometimes slower). The reason being, is that if the round stays subsonic, it doesn't encounter the transonic zone going downrange as it slows down in the air.
That's not the same as the heavy 60gr, or even lighter 20gr. primer only loads that can have cycling issues, but they're subsonic as well.
