Federal now markets American Eagle ammo marked especially for the garand. I have shot a lot of it with no problems. More accurate than greek ammo in my CMPicon "special". The hornady match ammo for the garand I have found has the 168gr amax bullet. It is expensive at about $30.00 per 20. Have not tried it. I am planning to buy one box to try. If it works well then I may work up a reload to duplicate. Shouldn't be that difficult as we know they use varget. I may try the N150 if I can find it around here anywhere. The hornady loading manual states they got the best results with that powder. It has a section just for the m1 garand.
