[QUOTE="BountyHunter, post: 921009, member: 12"] Couple things. 1. Factory chambers tend to be on the large end of SAAMI specs while custom chambers are often on the small side. 2. Your problem could be shoulder and could be the the lower body and your factory die may not size the body enough regardless of where the shoulder is. Measure the body of the sized brass. uou might try a small base die to fix it. 3. Tight is not always right. You must adjust the die to just bump the shoulder in spite of every thing else . [/QUOTE]
