Afternoon All, I'm struggling to find load data for 308 Win using IMR 4166 and sierra Game King 150gr SBT.
I've searched plenty of sites and just can't seem to find data for this combination. I'm aware that IMR4166 has a burn rate like Varget but would still like some official data to start from.
Any ideas?
