When that 90gr BSB load came out, I had high hopes for it. Figured it would be as good as the .223 64gr BSB bullet. Based on Nosler's specs on their site this bullet was supposed to expand down to 1600 fps. I though this load would be just like the gold dot round but like Xman results showed, the lead is on the harder side so it doesn't expand as well and it's minimum expansion threshold is way above 1600 fps. More like 1900 fps IIRC.Xman's thread has the bonded SSA 90 and it isn't that good. Maybe it works with 2 legged critters for LEO or .mil.
