Shot 5 rnds @ 100 yds of this last weekend and from my dpms lr65 and it was just under 1" outside to outside and pretty much identical zero...I didn't chrono it, guessed velocity at 2740, using BC for Hornady 140 bthp, and took it straight to 400 yds on a 6" steel and put 3-5 rnds on the steel in a row (no misses at that range) went to 600 yds on a 8" diamond and I was a tad high, missed at 1:30...adjusted and hit it a couple times...jumped to 1000 and was able to hit a 10" diamond 1 out of 3...misses were at 2 o clock Right over the corner of the diamond...adjusted my velocity to 2755 in my ballistic app...had 2 rnds left and shot them at a 14" steel square...first one missed about .1 mil left @ 9 o clock, next one i held right edge of steel and hit it dead center, steel swung straight back...winds were pretty gusty but the ammo seemed very consistent in elevation at all ranges...I really liked not having to change my zero...I did note that these rounds were fairl hot from my semi auto, all primers were a tad flat and had some cratering, seemed a bit hotter than 140 amax match but nothing unsafe...I'm in south tx and it was 100+ Heat index...I still have a few boxes left but initial results seem pretty good
