Are there any barrel suppliers offering twist rates slower than 1/12 without the barrel being special ordered/ custom made? Not sure how to ask this question but it seems the slowest twist commonly available for the rem 700 is 1/12 and e.r. Shaw did not offer a slower rate. Id like to try a 1/14 or 1/16 .30 barrel but it looks like $350 or more to obtain one.
