This year Sierra introduced four new SMK bullets:
.224 95 gr. with a G1 BC of .600
.264 150 gr. with a G1 BC of .713
.308 200 gr. with a G1 BC of .715
.308 230 gr. with a G1 BC of .800
Comparisons to older bullets (unfortunately, my .224 95 gr. photo seems to have gotten corrupted):
The .224 95 gr. bullet is noticeably longer and sleeker than the old 90 gr. as all of the new SMKs are.
Nosler also introduced some new RDF bullets:
.224 85 gr. with a G1 BC of .498
.264 130 gr. with a G1 BC of .615
.284 185 gr. with a G1 BC of TBD
.308 210 gr. with a G1 BC of TBD
Here is a 22 Nosler loaded with the 85gr. RDF. Note that the 22 Nosler case is the same length as a 223 Rem and this is loaded to mag length.
