Seating bullets causes the necks to bulge
Hello,
I'm fairly new to realoding...and a complete amateur when it comes to bottle neck rifle cases. I practised doing the Whisper ammo by doing dummies today....The neck sizing was easy...I just ran the cases thru the the F.L. die with 7mm and .30cal tapered size buttons...then I proceeded seating the bullets and experienced collapsed shoulders and a "micro bulge ring" just below the bullet. I used the 5.56 OAL. What did I do wrong?? The brass was brand new. Help me!!!!!
