When you say the last bullet does not feed all the way and causes a jam what exactly is it doing? Not being stripped out of the mag, nose of the bullet jamming into the feed ramp, Round going into the chamber but not completely going into battery, ect.

It is strange that 7 rounds feed fine but 8 do not. If it was a problem with a weak spring or the follower catching on something you would think it would happen on the last round no matter how many rounds were in the mag.
Lastly, did you load up the mags and let them sit a few days fully loaded? I normally do this with all new mags to seat the mag springs. I have had feeding issues with new mags before I started doing this. You may want to give that a try.
