[QUOTE="davewilson, post: 227670, member: 4491"] Roy, great stuff as always. my only thought to your results would be the reason the bullets tumbled wasn't the lack of speed, but lack of rpm's. just as a bullet has to spin at a certain rpm to go straight through the air, it also has to spin at a certain rpm to go through "media". it takes more rpm's to stabilize going through media, than it does through air. wasn't Kirby gonna build a gun for every caliber so we can test all bullets in regular twists at 1500 fps?
