You are far too modest. Even 3-6 inch groups is very respectable at that distance, but getting them touching, is skill, even with perfect hand loads in a vise.
I'll be honest, I have only shot 3 different brand ammo out of my fal so far, and the one that I expected would perform the least consistently, has been better than the other two by a very noticeable difference.
The steel case wolf 308 has done the best for me, while the Federal lake city xm80 is plenty good enough for just about anything and putting meat on the table, but the Turkish ZQ1 ammo that I bought at walmart looks more like a shotgun pattern than a rifle group.
Everything I have been told in my Fal is to keep the ammo below 150gr. But then again, I've heard the same with M1's and the likes too because of gas pressure, despite the fal having an adjustable gas return. So to play it safe, I've stuck with the lightweight stuff, and besides, mines' more of an old war horse than a bonafide match rifle, so I'm pleasantly satisfied with it's performance. Either way, I don't think either of us is going to starve anytime soon. But I've already made a mental note not to place bets going up with you side by side LOL
