anyone have any problems with runout on this chambering?im thinking about having one built but i dont the really short neck,seems like the 7x300wsm is the way to go,to get a longer neck.any and all info is apreciated-tia-dave
Donít sweat the neck length. Runout comes from your reloading dies and a longer neck wonít fix that. The neck has to be long enough to positively hold the bullet during handling and the 7 mm WSM has more than enough. You gain a little case capacity using the factory round and there is none too much in any short mag.
You will be able to more easily get great reloading dies (Redding Competition Bullet Seater and type S bushing dies) in the factory round and that will help with bullet run out.
