Some US 1000 yard ranges don't even allow the 168 gr Sierra MK because of instability.
I saw a shooter doing well with an old production lot, but when he bought new, he could not hit anything.
Better to get the 175 SMK or perhaps a 155 Scenar.
Berger bullets are good, and shooters are loading heavy; a friend really likes the 185 gr Hybrid.
ADI powders seem to be the most available in NZ, likely because they are made in Oz.
I load Varget, which is the Hodgdon US sales version of AR2208.
AR2206H, our H4895 would be ok. Original AR2206 is probably too fast burning for best ballistics.
If you can get Alliant, Re 15 is good; and, as said IMR 4064.
