typical ak if it loads and fires SOMETHING is probably getting ejected . I've had a few brass cases torn in half and ejected [S & B ammo] by a riley ak 47 with less than 1 k through it . I had bought a case of sellier bellot FMJ because my RAS stash is getting low and hard to find , it has to be non magnetic for some of my range rules . The front half come right out with very little effort using my home made case extractor , i was going to just use steel case stuff because that never gives me any problem in my aks but then i go no go gauged it ........failed badly . 3 years out of what i thought was warranty and riley said send it back and they will fix it for free . to-days safety tip is use those gauges on your semis
