[QUOTE="db2989, post: 3084539, member: 129570"] So here is a question that I have found little evidence to point me in the right direction. I'm currently building a precision ar-10 and I am having a hard time deciding what barrel length to go with. My plan is to use either a 11 or 12 twist however what i need to know is how many rotations should the bullet have inside the barrel to be properly stabilized. So for example if I go for the 12 twist would it be worth having a 24" barrel to allow the bullet 2 full roations in the bore or is 1.whatever roations fine enough? Im not concerned with the overall length of the rifle this is going to be a range toy more or less, but should the bullet have more roation time in the barrel or am I over thinking this? Thanks for any input... [/QUOTE]
