Hi from New Zealand.
I've just signed up after reading right the way through this thread, I use a Tikka T3 in 308win and my reloads at the moment stand at:
Hornady 165gr SST
46 Grains of Varget (also known as ar2208)
CCI primers
Federal Brass
They run
2780 FPS (measured @ 1 meter - 22 1/2" barrel) and they shoot anywhere from 7mm to 15mm Center To Center (1/4" to 1/2") depending on how good I'm shooting that day :P
