[ARCHIVED THREAD] - ejection problems

Posted: 8/10/2008 8:53:22 AM EDT

I'm shooting prvi partizan 158 gr 9mm ammo from an Integral suppressed AR upper.
The spent cases are not ejecting and getting hungup in the bolt. My question is the
9mm buffer too heavy to cycle this ammo? I have no problems with 147 gr. The 158 gr
is very quiet at 850 fps. I'd like to stick with this ammo.
Any suggestions?

Thanks,Chris
