Which one? The 64gr or the 75gr?
If the 64gr, then this should help get you there:

Expansion threshold is below 1800fps or roughly 200yd from a ~10.5" barrel.
I do not know for the 75gr at this time.
7.5 or so.
OP, FWIW, WS6 is M4C's 64gr Gold Dot Expert.
Why do the loudest do the least?

I did not know the man quoted above, and joined this Forum after his passing. He seemed to be a leader of men; both spiritually and physically. Someone we'd all be proud to emulate.
I'm not an expert, but I do know some people, and I did get some limited data from personal observation as well as ammo I sent to a few others. The 75gr gold dot is pretty impressive, as is the 62 and 64.
As of now, there is no official minimum for 75gr expansion threshold, however, to my eye and observation, it's identical to 62 and 64gr in material and construction except that it has a longer shank below the cannelure. If this is all, then it should expand down to 1600ish. That said, I've seen pictures of 62gr gd taken out of deer that arrived at well over 2k, and barely deformed. Bullets do odd things.

WS6- any info on why Speer stopped making the 5.56 GD load? I heard a rumor as to why, but would like confirmation.
The obedient always think of themselves as virtuous rather than the cowards they really are.
The 24455 was discontinued because people were running it in .223 or bad chambers, having problems, and blaming Federal rather than the manufacturers of their good-as guns. Further, any additional gain over the .223 loading (22446) wasn't significant enough to justify two loadings for the same bullet.
It was restricted in part for the same reasons, but remained available to the commercial side while in production.
