Hope this opens,
By changing the weight of the bullet 5 gn. {70 to 75} the stability factor goes from poor = ORANGE to good]GREEN
Which dosen't make any sence ???:killingpc :killingpc only thing I can think of DAMN COMPUTERS

What's the weight range for that cartridge? Twist for that diameter? 5 grains is apparently a big deal for a .22-.25 caliber boolit. Change the velocity of the 70 grain boolit and see what you come up with.

It's little brother the NOE .224-55 is going 59.0 59.5 so this one {.224-60} I'm SWAGing this one should throw about 66.0 which makes matters even worse, at .750" long and weigh 66.0 gn with a 1-12 twist will require 1700 FPS
BUT the weight shouldn't matter, Green Hill dosen't require the weight of a bullet to work. :killingpc

True but the weight will determine the length, to an extent. I wouldn't expect 5 grains make a huge difference but I don't work with anything that small and my math skills aren't sharp enough for me to disagree with that calculator. When in doubt, shoot a handful of them and see what happens.
