What have you guy found to be the most accurate ammo for your 10 inch 416?
Only experience was with BH 77 grn. from 14.5" bbl. Excellent results.The military did a test a few years ago on the 5.56 in a SBR. It showed that the heavier grain bullets had better accuracy. Not going to get into which brand is better, just passing on the info.
Does anybody know if this round is available in the US? I looked at Widners.com, but could not find any. Also tried to look for clone equivalents (55g OTM), but to no avail.The IMI 55 grain BTHP Match round (if you can find it) shot sub 1 MOA groups at 100 meters from a 10.4" HK416 in a test fixture after firing 12,000 rounds during lot acceptance testing in 2004. Not sure if this is available in the US but it was by far the most accurate round from that platform, even better then the 77 grain MK262 round from Black Hills.
