I had the pleasure of taking my 223rem UV to the range. This type of rifle and load are new to me, but I think it's going to work out. Fired ard 60 rds. No misfires and no FTE; action popped open three or four times. I had to start on the 50yd range....remington 55grfmj was not to consistant out of this new barrel. Winchester 55grfmj [Isreali] was much better, in fact, had a couple of 5 shot groups covered by a quarter. I moved over to the hundred yard range and was surprised to see poi was 8 inches higher than the 50yd poi!? Crosswind was picking up [7-10mph] and the best grouping was ard 2 inches with Win 45grjhp, which is probably not to wind resistant. Blackhills 40grnosler not too good, either. By now I think this new barrel is fouled pretty good....looks like fine copper lines just in side the muzzle in the groove/land juncture.

Observations???
...8 inches higher at 100yds than 50yds was surprising.
...I may hand lapp this barrel just to speed break in. When cleaning the rod and patch seems to be stop and go down the barrel, not really a smooth one piece motion, also seems tight ahead of the throat for five inches.
...The receiver face is getting a 2 line Engraving below the firing pin by the ejector no doubt...SHOULD I relieve the back of the ejector to minimize this engraving or is this normal on this rifles?
