I do not know what kind of silencers you are used to using, but if you use one made from metal that is filled with baffles, then they will last thousands of rounds without degradation unless they are mounted out of alignment or over heated. The only silencers that wear out quickly are those that use wipes or mesh.
There is no need to use subsonic ammo in a suppressed weapon. A silencer will reduce noise by a similar amount no matter what kind of ammo is used. While a 308 rifle may be 165 decibels with standard supersonic ammo, and 155 decibels (ten times less intensity) with subsonic, the silencer will reduce the noise about the same even though the rifle with the subsonic ammo will be much less noisy in the end.
The main reason subsonic ammo (ex 308 or 223) is less noisy is that it uses less powder than the same cartridge with a large charge for supersonic loads. While there is a sonic boom made by the high speed bullet, since it does not pass he shooter's ear, it is much less noisy than the muzzle blast.
I design and make silencers on ATF form 1's. This is what I have learned form personal observation.
