22 ARC twist rate

Wanting to build 22 ARC bolt action rifle.
What is the optimum twist rate for the 62 EDL-VT bullets out of a 22 ARC bolt gun with a 22" barrel @3450FPS.

Thanks!!!!!!!
 
My 9 and my 8 both shoot them fine. In case you ever want to shoot 70-80 gr bullets I d give an 8 twist serious consideration. If you re certain you ll never go heavier than 62-65 then a 9 twist will work fine. The 62 VT is nearly as long as a 75 Eldm just so you know.
 
Guns and Gunsmithing; exactly. Velocity plays a role but it’s pretty minimal. Elevation (air density) has much more effect than velocity.

The 62 s did shoot well enough in my 9 twist Vanguard that I got 5-10 400-550 yard rockchucks back in May. Surprising how well they carry. The 3100 fps helps a lot too.
 
When there were no bullets heavier than 68/69's, the 9 twist was idea. As bullets got heavier and longer, the twist needed twisting a little more. You can hardly find a new 9 any more.

I pushed them hard in my 223AI 9 twist, horrible accuracy. Or slow for that matter. With 53gr VMAX nice tight groups in that barrel.

My ARC is 7.5 twist and shoots them very well.
