I have been toying with the idea of building a 6 creedmoor and I like what I hear about the dracos barrels but they only produce the 6 creedmoor in a 1-9 twist and I want to shoot the 105 hybrids so I asked about a 1-8 custom barrel. Here is their response: Hello Matt, At this point we do not provide custom twist barrels. I understand that our barrel twist rates are a little confusing to say the least, however keep in mind that we are not using the traditional style rifling. We are using Caudle Rifing. Caudle Rifling is a state of the art polygonal hybrid style rifling that has interesting characteristics. Our twist rates are designed to be the optimal twist rate for that barrel system. Nick Does this sounds right? My understanding was bullet stability was a direct relation to the rpm's after the bullet leaves the barrel? Maybe I am wrong?
