Went from Aimpoint to Eotech, and just got ACOG TA33H-G for my E2S 16" carbine.  Any tricks, tips, advise on zeroing at 100?  
It is 3X, so maybe my expectations of achieving tight groups are not realistic considering I am not an expert shot.
After two trips to the range I am still shooting 6 MOA or so using XM 193 55 grain.  I use the gun to shoot pigs that are reeking havoc
on my dove lease in the milo fields and I do take 100m shots often.  Used to use a 270, but much more fun with the AR.  Any help
would be appreciated, thanks.

Sight in at 25meters using the 300m point of aim in the ACOG.  Then fine tune at 100.

Use sandbags to support the rifle, and focus on your trigger pull.  Smooth straight pull to the rear.  Keep holding the trigger to the rear and release only after the shot has been fired.
