just curious why this is worth so much $
Sarcasm detector fail?
It is green tipped M855, has a steel core penetrator… don’t worry you don’t want any

Perhaps, but reading his post again, I still can't decide... mmm, maybe you're right, my dectector has been a little wonky lately. I bought these two girls drinks the other night, and it turns out they were lesbians, because neither seemed to like me. You'd think I would have picked up on that too.

Apparently your ###dar is broken too…
This is not the ammo you are looking for…
It depends on the AR-15/M-16 series as it relates to bullet weight. I cannot speak to specific experience with current PMC’s version of M-855 62gr round with penetrator, however, std M-855 or SS-107 was intended with 1/7 twist barrels and it is OK with 1/9 twist.
As for 55gr FMJ, usually copper jacketed, lead core also known as M-193, it is intended for the original 1960s 1/12 twist barrels . It is generally OK with 1/9 as well
If you mix the groups, say M-855 or SS-109 in a 1/12 twist barrel, accuracy goes right in the toilet and it unsatisfying and a waste of ammunition. I tried it once and I stopped. No fun with a 1/12 twist “shotgun” at 300 yards
Hope this helps. With 5.56mm bullet type/weigh and barrel twist is a huge accuracy factor

still dont get it...cheap stuff does the same
Please point me to cheap 62gr or heavier bulk ammo that matches Acog and Elcan BDC out to 500m and I will happily buy that instead of M855.
I guess you don't shoot beyond 200m and don't have an optic with BDC calibrated for m855.

correct
I have an ACOG TA31-CH which is BDC'd out to 600m. I used it on a Swiss Arms (19.7 inch 1:10 twist) with superb accuracy out to the 550m gong using both 55 gr and 62 gr. It now sits on my SR-15 (16" barrel 1:7 twist) which I can't stretch out anymore (stupid f*cking restricted laws) I try to shoot green tips exclusively through both but here is the info I based my sighting in on:
From the AR forum
For a Flattop 16" firing M855
Sight in 1" high at 100. You'll be a half inch high at 200 0.5" low at 300 and under 2" off BDC out to 600.
For a Flattop 20" firing M855
Sight in 0.8" high at 100 (or sight in at 60). You'll be 0.5" high at 200 and then dead on the BDC to 500 where you'll be 3" high and 600 you'll be 8.5" high.

Meters. The ACOG's are calibrated in meters and the sighting in info is in meters.
