I have a 7 mag so everything from the factory spaces off the belt. If I had bought new brass I would have had to fireform it anyway so I could resize off the shoulder. So this is cheaper than plain RWS or Norma brass plus I dont have to load it to fireform, even cheaper. The BC on their bullets are low. The 177 7 mm rounds were .385 or something like that. So Im just going to shoot them to bring a new scope and then fireform the rest.
