Thank's for your response Rick, I had already called Shilen, they said to refer to the bullet makers web sites for twist rate, or ask on a forum. Thank's again

I would like to build a 204 upper and will be shooting lead free bullets due to the state of California restrictions. Shilen lists a 1-9 twist and Midway has them in stock. Will I be able to shoot the lighter, lead free bullets with a 1-9 twist.

Thanks
