I was told by a reputable source that Green Mountain is no longer making muzleloading barrels with a fast twist any longer, just patched round ball barrels. If this is true, how can Pecatonica and others still continue to offer rifle kits with fast-twist barrels? Can I expect to get one of these kits and find that it has a slow twist designed for round ball? I can't find the faster-twist barrels on Grenn Mountain's web site either. I was thinking about getting a kit for a target rifle with a fast-twist barrel. Could I end up with a target rifle but with a slow twist not designed for conicals?
