Sierra 60g TMK in the AR

Anyone loaded these for the AR? They seem pretty long.

I have not used the tipped ones in the 223R, but have in my 6.5 CM. Most of the tipped ones state what twist rate the barrel should have ti be accurate.

I've run some in a bolt gun. Sierra indicates an COAL of 2.260, which would fit most AR mags

Thanks for the COL confirm. That's what I had seen somewhere.
