FA91 help

[brett T]

I have a FA91 that has been shot thousands of times with out a problem till now. Im having issues with the firing pin not hitting the primer hard enough and it miss fires I cleaned it and got it running again but on the second clip it did it again. I did notice that the point of the bullet had damage to it I was using Winchester power points for the first time Im thinking that it may not like this ammo I cleaned it again and am going to try to go back to the basic .762 I was using before.
