Jacket shedding might be speed related (slides off the back end

),
But RPM pretty much defines stability.
There are examples of fast twist barrels shooting short fat light bullets really fast, but not the norm.
400,000 RPM and most bullets don't go far

What was the twist of your 4100fps .17 ?
Actually the question should be what was the RPM you were shooting?
(between 250,000 and 300,000 ?)
The 0.086" radius of the .17 bullet should hold up better than a 0.112" radius of a .224" at high RPM.
