Bore size on ar9 carbine barrels

[Shingle]

I spent the day today slugging the bore's on 7 AR9 carbine barrel. This was done to see what it really was .354 to .3543 this explains why bullets sized .355 shoot so well in my carbines. Is this common or am I the odd man out.

I have not slugged mine, but I have been sizing to .356 and I have had no leading...yet
