I have searched and can't find many review or info on these bolt bodies. I have talked to a few people and decided I wan't to get one and have one question. The spiral fluted ones are out of stock at midway but they do have ones with straight flutes. I know from reading around that people don't recommend straight flutes because of how they can catch and mar the brass. My question is since the PTG bodies are really just a lightly ground flute, would they be shallow enough that it wouldn't have any negative effects associated with straight flutes?
