I'm with you, I like to full length resize my 7mm brass because it is easier to chamber in hunting situations, especially when it gets real cold. 12x is WAY too many times if you are full length resizing. I was wondering why you are on the 12 time...Are you using one or two boxes of once fired factory ammo? If so, bite the bullet, and purchase some inexpensive Winchester or Remington never fired brass. They come in bulk, are fresh, never fired, and are fairly inexpensive. They run 10.49 for a box of 20, or you can get 100 rounds for 40.99 right now at midwayusa.com. You can cycle your brass much better, and cut down your firings per piece better. Personally, I'd toss them after 5 or 6 rounds.
