My new 2.5-8x36mm M2 came with the 7.62mm 168gr @ 2650fps dial.

I'm toying with the idea of ordering a custom dial. The factory .223 offerings are 62gr @ 3100fps and 77gr @ 2750fps. Those aren't going to happen from my 16" barrel.

My tendency is to pick a Black Hills "blue box" offering. I've got a 1:7" twist, so heavy bullets are fine. Is there something that makes the most "sense"? I handload, so I expect to be able to duplicate (or close-enough) whichever load.

55gr? 69gr? 75gr? 77gr?

I suspect I'll mostly be shooting 55gr, but I'd probably only really use the dials for long-range so I'd want a heavier / better BC bullet...

I went ahead and ordered the 77gr @ 2750fps BDC dial today.

Good news -- my 16" carbine shoots the MK 262 Mod 1 @ ~2700fps.

The bad news -- the BDC dial I ordered is the "low profile", and apparently I need the "tall" version.
