[QUOTE="royinidaho, post: 324780, member: 2011"] Tank, I've been really disrespectful to a 3 groove Lilja w/an 8 twist. A little more than 8#s of powder through it at an averange of ~95 gr a pop. And she still have very little to none copper fouling depending on which bullet is being used. I would say from that experience that a 3 groove 11 twist in 30 cal would out last a couple of generations of liltanks. Shrink the bore to .277 then robust bullets/jackets are a problem at extreme velocities. [/QUOTE]
