.300 WSM ???
A friend that I was talking with told me of his recent unusual experience with this cartridge. He has extensive reloading/shooting experience from .243 to .458 Lott. He told me that while loading for a new rifle in .300 WSM, he was having trouble seating bullets, the problem being that some times the neck or shoulder collapsing when attempting to seat the bullet. He said that the brass was new Winchester, and that he also had problems getting it in the RCBS sizing die to begin with. (He runs new cases through the die prior to loading the first time.) I thought that maybe the brass has necks that are to thick and that after sizing they are to small to get the bullet started (bullets are Barnes TSX 168gr.)
Or that his expander in the die is to small, but that would make it easier to get the brass in the die the first time, wouldn't it?
He said he chamfered the mouths and even lubed them and was still having problems seating bullets. Anyone else have similar experience? I was thinking of buying a rifle in this caliber, but may change my mind and get a regular .300 Win. Mag.
