69 gr smk bullet, in 223. What I SAID was a 60 gr Nosler Partition over such a charge, in Win White box brass. The Partion is nearly 3/16" shorter, so it WILL seat atop such a charge. Idiots can't READ. Just cause I ALSO mention the smk bullet, at 100 fps less than the Nosler, does NOT mean the SAME powder charge was used, dumbasses. Of COURSE either less powder or a different powder was used, with the heavier, longer smk bullet. what a bunch of twits you are.
