Barnes TTSX for .223 rem 55gr

I had recently bought a box of the Barnes TTSX 55gr for use in my AR 5.56mm. I couldn't find a set COL for the round. I called Barnes a second time to discuss this. I explained to the guy that last time I called I was told to use a COL of 2.180 and that that length sets the ogive of the bullet into the neck of the brass. We came to the conclusion that a COL of 2.240-2.230" is the way to go. I attached a pic of one round I loaded to the COL of 2.240", which places the top of the neck right to the top of the Cannelure. Im gonna test this hopefully this year.
