Bought from Midway, Sierra makes 2 versions of this bullet. I ordered (and returned) a 250 count box and they have 107gr HPBT-CN on the box. Product #1570MP. These are a copper/nickel jacket and seat .020" deeper in my chamber according my Hornady gauge. Midway does not say anything about the copper/nickel. The are a dull copper color and the ogive is obviously different.
My 100 round boxes I've been using are #1570 and have no CN.
I would have tried them but I have a great load worked up with the all copper jacket #1570 tuned up for a set COAL.
