[QUOTE="Window, post: 2656947, member: 88485"] I’m in need of a little advice as to how figure out an issue I’m having with a Weatherby 7 mag. I’m starting load development (for a friend) using the 120gr Hammer Hunters and here’s my dilemma. First of all the brass is once fired factory ammo through this particular rifle. My process is to remove primers, clean, anneal, and size full length with .002 shoulder bump and trim. I check every case in the chamber with the firing pin removed to make sure there are no anomalies. Now here’s the dilemma, when I seat the bullet (20 thou under mag length) the bolt is stiff to close. On nearly all Weatherby’s, I start there and with the excessive free bore, it’s not even close to the lands. The OD neck measures the same as a factory round loaded with the TSX and it chambers fine. I’ve completely colored a case with a sharpie and there are no marks whatsoever. Again I’ve taken every measurement possible and have no idea what’s causing the issue. Also, I’ve cleaned the barrel and the throat to perfection that’s verified by with the bore scope. Any advice or answers is more than welcome as I’ve thrown in the towel. [/QUOTE]
