[QUOTE="dfanonymous, post: 1572826, member: 97050"] Well for starters, it depends on the length of the bullet (longer bullet equals more weight usually) but it’s the length that plays a factor in stabilization. The heavier (mo longa boolets) will get more benefit from a faster twist to keep stabilization. That’s the jist. Where I’ve been coming from is that plus or minus 10 grains of 200 and especially lesser grain projectiles is that going faster like a 8 twist on a .300, you’ll end up getting more drag with the nose up belly flop that the bullet will do as especially passing transonic and ultimently less consistancy in your dope for the entirety of the cartridge to bullet dynamic performance. A faster twist looks good on stability calculator but it has other effects that just haven’t been mentioned. Especially if you shoot low to high elevation in really cold to 120 degrees heat. [/QUOTE]
