[QUOTE="Greyfox, post: 2274590, member: 10291"] I have not seen evidence of this either comparing them with testing 50 yard increments to 200 yards where supersonic loads have already passed to subsonic. IMO, the greater benefit of subsonic target ammo over the high velocity ammo is that being match grade, it generally has a much tighter ES which does benefits at long range. I have stuck a happy medium using the Federal GM HV Match at 1200FPS. It produces the best results in my rifle at 200-400 yards. I do believe studies have shown that for target/match shooting at typical ranges(50 yards), a bullet passing the sound barrier at or near the target will destabilize the bullet and effect the very fine target accuracy requirement(sub 1/4” accuracy) Much past this range, the poor ballistics of the low BC rimfire bullet appear to supersede and overcome this effect for shooting at the longer distances, and the differences are nil or none. IMO [/QUOTE]
