Just a little.......  

OK, I did all I could do. The newness of the Tavor got me. lol  No, not what you think, I didn't shoot the chrony, but I was aiming so high to not hit it, it took about 4 shots that didn't read, and 2 errors from only going over one eye close enough. So, I got 5 shots in a row that were good. Also, I don't see the lot number, but if anyone would know where to find it on the little plastic 120rd ammo cans, let me know.

If OP wants to copy paste the results and put in the original post that might be a good idea.

I hate I couldn't get any more than that, but that's what it is. I'll get used to the height over bore thing and get more data sometime when I get some more ammo. I will test anything else if anyone wants me too. I want to try different loads in this thing , so I am happy to test stuff out and report back.

3150 out of a 16" barrel sounds like normal M193 spec.  Love that extreme spread though.

Test

16.5 inch barrel, but I think you're probably right.  Seems like it's loaded as hot as before.  Bought some new, 16' black box XM193 from Cabelas and will be trying it soon.  Hope it delivers the goods so I can order more.

More of the same crap I see...
