why do .223 guns tend to have 1 in 7-9 rate of twist, which allows for heavy bullets, while 22-250s seem to all be 1 in 14, which limits it to 55gr?

still doesn't make sense. why would you want to use a less accurate, lighter bullet, which looses energy quicker while varmint hunting? cause the early trajectory is flatter?

When hunting varmints, the opposite is true so a flat trajectory becomes relatively important.
Why do bullet manufacturers sometimes recommend a twist when they don't know what cartrige and charge might load?
Actually since the spin rate (rpm or revolutions per minute) is what is actually doing the stabilization, muzzle velocity does play a part.Because the required twist is not relative to velocity...
