Wes, that is the thing about this bullet. The Texas Troops has three grooves and is a nose cast bullet. Can't be a short pour and I can't see any markings showing it being cut off. It does have a large push in the base skirt causing it to be out of round. The profile and everything leads to the Texas Troops (Cove Creek) but that is why I have it listed as an unknown. I am not that familiar with pouring bullets and is there something that could happen during the process on a nose cast bullet to prevent the lower ring from being filled. I guess something could have been in the mould or possibly a bad mould, don't know.
