Need some rifle twist expertise....
I know that just like with bullet diameter vs case volume, velocity vs twist rate can also reach a point of diminishing returns. This is hypothetical, but I am hoping we can have a good solid debate and I can get some solid answers.
If you were pushing a Berger .224 90gr VLD down a 26" barrel, at between 3,800-4,200 fps, would you need a 1:7 twist, 1:8 twist, 1:9 twist, 1:12 twist, or 1:14 twist?
I am thinking 1:12 twist, simply because barrel length and bullet velocity would be traveling SO incredibly fast that the really slow twist rates (1:7-1:9) would hinder it, or cause the bullets to come apart in mid-flight, or as soon as it exits the muzzle... And that the 12" twist rate would stablize the long skinny bullet just fine because of the incredible velocity it would be traveling down the barrel at...
Any help and input would be great. Thanks!
