You didn't mention caliber, another factor in twist rate.Bullet length is also a factor in the twist rate required to stabilize a bullet. A 220 gr round nose is pretty stumpy compared to an ELD-X
"Stumpy"? I suppose that's a matter of perception.
I honestly do not have - couldn't find anyway - a 220 grain round nose bullet to measure. However, my .308" bullet horde did turn up some heavy rounds. I had good results with a 225 grain Hornaday HPBT (of 1.580 inches length) fired using an M1917 barrel. No shot holes showed any hint of yaw.
The original question was 'will a .30 caliber 1:10 twist barrel stabilize a 200 or greater bullet?' I say yes and justify my answer. Do you have an actual rebuttal?
