Re: Best range to test bullet stability
When I use the twist calculator, I check for worse case altitude and temp. The lower the altitude and/or temp, the less stable the bullet. A stability factor of 1.1 or better should be stable enough for flight through the air and paper punching. A stability factor of 1.5 is more ideal and recommended for terminal performance stability inside 500 yds.. So it's possible to have a bullet that appears stable when target shooting that might have terminal performance issues inside about 500 yds. The farther down range you get, the more stable the bullet becomes. If your bullets are making nice round holes @ 500 yds, they should be stabilizing OK.
You will never know how much it has cost my generation to preserve your freedom. I hope you make good use of it.
