I'm shooting CMP ball ammo. I'm noticing that my rifle is ejecting the brass forward rather than to the right.
Stop over thinking this and be happy. I have a 308 Win Match Garand that ejects brass right into my forehead. I have to keep the brim of my cap low, just touching the rear sight peep, to keep brass from hitting skin. I have come back from matches, with semi circular, full circle cuts on my forehead, oozing blood, from sharp case mouths that ejected directly back, hit my forehead, because my cap brim was too high.
I have shot many Garands, many thousands of rounds through Garands, some toss their brass to the right, some toss most of their brass to the right, others toss brass everywhere. If your rifle is tossing brass forward it is likely due to the operating rod kicking the ejected case forward, and that is most wonderful. Wonderful to the shooter on your right. I have been warped untold number of times by the shooter behind me, his brass hitting my back, back of my head, etc. I have been burnt by Garand brass, and it don't tickle.
What matters is that your rifle functions reliably. Ignore all statements that the Garand is supposed to...... If your rifle goes bang, ejects the brass, feeds the next case, goes bang again on demand, then it ain't broke.
