I have a set of 30" Hastings 12gauge barrel blanks that I am going to build into a double 12 bore. The twist is 1-34" and is optimized for Hasting's saboted slugs. I'm just in the parts gathering stage now. Am thinking of building it on a JP Sauer double...when I find one suitable to convert (or ruin trying).
