[QUOTE="308 nate, post: 299903, member: 1920"] Understood. If you are using Norma brass in a 7WSM use 300WSM brass. So when you size it down you have a false shoulder to head space off of. This will be like fire forming an Ackley..exaggerated as you will be blowing the whole case forward. I also recommend seating the bullets to touch the lands in your fire forming as this gives you an extra head space stop. Be careful. Only thing I do to Norma brass is chamfer the inside of the neck and ream the inside of the primer pocket. Not to say more can't be done. I just have a hard time holding onto a piece of brass for that long:D Brux is an excellent choice!! I have used around 100 of them and haven't had a bad one yet. Not to mention they are great to deal with! I would recommend a 9 twist. If you are shooting primarily 180's I would go with a 8.6 twist. 308nate [/QUOTE]
