will a 1in9 twist in a .264 stabilize the hornady 140gr. sst bullet? how about the 143 eldx bullet?

Yes it will.

Are you doing a custom barrel?

i am talking about a remington 264 mag.barrel...Ed

I've shoot 140gr Amax in a 9 twist 264 that shot just fine.

Looks like the 143 is a little longer, FYI
