Help with 300 Weatherby brass resizing problems
I am new to reloading and need some advice on what I am doing wrong? I have a 300 Weatherby that I just bought and have some brass that I shot from a different 300. After full length resizing the brass it will not chamber into my new rifle, but the brass that I have shot in my new rifle will. All the brass are from the 3 boxes of factory Weatherby ammo.
