I just got mine from Titan Reloading and plan on using it for plinking loads in a Glenfield 30 microgroove (30-30). There was a monster of a burr on the base which I removed with a pocket knife. After I did that it occured to me to ask if this mold was designed as a bevel base. Even if that is the case I would have removed it so the question is purely accademic.
