I shoot a 20" barrell Rock River HBAR and can achieve 1MOA with different low cost ammo at 100 and a bench.  I have been invited to shoot in a sniper match which will have targets out to 4oo yards.  I have never shot past 300.  I have my rifle sighted on at 50 and about 1 1/4 inches high at 100.  My trajectory tables do not go past 300 yards.   Please route me to some trajectory tables or provide your own experience.  I will be using a scope for the sniper match.  I generally shoot 55 gr bullets but I have a few 62s.  I would like to purchase some 69s at a reasonable price any suggestions on this question?  Thanks

2.4" high at 50yds
6.5" high at 100yds
11" high at the 200yds
11.3" high at 225yds
9.5" high at 300yds
