ive shot a bit of GA Arms reloads as well in .223 and had no problems at all either. Now wolf on the other hand. I was home in NC this past weekend and i shot 100 rounds of PMC .223, and had 40 rounds of wolf. I first shot 2 mags fully loaded with PMC and it shot awesome. Then i loaded 20 rounds of wolf in to two magazines. Took my first shot and noticed that the next round would not feed. I assesed the situation, and cleared the jam. Took another shot and the exact same thing. So i dumped out the wolf and reloaded with PMC. And it shot fine everytime... no jams, misfires, feed problems or anything. so here is a big to wolf ammunition in .223. Never ever ever will i buy it again. /end story lol
