    Having some feeding issues with my AI AICS mag. I drilled out the binder plate and welded up the holes, not sure if I caused this issue or not. Can someone get me the measurements inbetween the feed ramps on the front and back? It seems mine has a slight taper getting closer together toward the front making the round dive a little causing it to hit the feed ramp and not want to go
     
    The mags I have are 0.410” to 0.420” between the feed lips

    They should be parallel for 308 based stuff, but I have found that cartridges with less taper like x47 and Creedmoor feed better if you open the front slightly, maybe 0.440 or so
