Not necessarly so. The heavy bonded bullets have varying BC’s among specific offerings, meaning some of the 62gr offerings may be better at extended ranges than some of the 75’s. Hornady TAP 5.56 SBR 75, for example has no boattail and a wide tip, leaving lots of BC on the table. It also has a relatively low muzzle velocity (like .223). I’m sure it wrecks shop at close range.
There are probably 75gr bonded rounds that are better at long range than their 62gr counterparts, but they elude me so far, personally.
