Heh - a good excuse to post a weekend range report on the IMI M193, including a second round hit at 700 Meters with the lot I received last week.
I was running my SPRish 18" Noveske build with the 77 gr SMKs it likes on steel; for S&Gs decided to check the standard come-ups with the IMI 55s.
I was surprised to see the 200 meter hits were very close to my normal 77 gr zero with the NF 2.5-10x32. Walking it out to the longer ranges, the IMI was ~3 MOA high on the 500 Meter gong (8 MOA needed Vs std of 11 MOA).
At 700 meters (12"x18" gong), using a reticle hold of 20 MOA (Vs 20.5 normally dialed with the 77s), the first round ranged just off the left edge and ~2 MOA high. 18 on the reticle plus one right and the next one was a hit. And I know when to just smile and quit.
It's not match ammo, but "most" guns shoot the IMI M193 very well in my experience. The current lot is hotter than when I first started using it in the early 90s, btw. It's zippy in the 18" SS (1x7 NATO chamber) and definitely 5.56 pressure. Bright marks on the case head, but no brass flow into the extractor cut.
