I ran some cci subsonic for the first time through my hk Mp5 .22 and after every shot a FTE occured... I have put several types of ammo through her and had no problems.. Is this common with subsonic ammo?  And if so is there and thing I can do to prevent this from happening?  Thanks in advance

I had the same experience.  The one exception I found that works pretty good is using the Aguila sub-sonic 60gr rounds.  They work just as well as the high speed rounds.

Thats the nature of subsonic. Try some standard velocity stuff.

They use less powder to achieve the lower velocities.  Thats why the action wont cycle.

Try CCI Standard velocity ammo. Blue box. States 1070FPS on the front of the box. Stays subsonic is everything I own including an original 16" Spikes, 10/22, P22, Buckmark.
Cycles all my semi autos. This is very consistent ammo IMO.
Swapped a box of this for a box of Gemtechs SILENCER SUBSONIC .22LR AMMUNITION (@ nearly 2x the price) with my gun dealer and neither of us could tell a difference sound wise, suppressed.

Same with Winchester DynaPoint. Its standard velocity and side by side with subsonic ammo, there is no difference.
