Thread: Bullet twist blow Up Numbers

interesting way to get it...
done this one manytimes before

if we round figures for ease
270 with 1;12 twist...instead of 1: 10 but guess can add 20% to final figure to be accurate

3000fps =3000 times spun per second x 60 seconds per minute 3000x60 =180,000 rpm chuck extra 20% on that 18devided by 5 x6=21.6 chuck zeroes back on
216,000rpm
thats one hell of a lot of spin and centrifical force trying to pull projectile apart....
you fellas with fast twist barrels of 1:8 thats a full 25% faster/more pull
Ive mused on this one before,in theory a faster twist should make same projectile expand more than slower twist barrel....
